Why the H*** did I not think of that....
Phil you are a genius......
....I actually set my flywheel on the pointer .....then crawl underneath to spray paint the flywheel black then draw a yellow line on it for TDC..... ....... now I will not have to crawl underneath anymore..... which is a good thing as I get older..... I still can't believe it.....even smart ass GM engineers never thought of that.... Thanks a million...... ...... as Rob said we will adopt you if need be....... Bob

Back to the rough running
Couple of things that I have really noticed down here with the E10 fuel, it does go off (stale, water logged, what ever) very quickly. The best cure I've found is an electric fuel pump. Both big trucks have electric fuel pumps and letting them prime the carb before trying to spin the engine makes all the difference. They don't seem to care if they have sat for a day or a month both of them also are reasonably fresh rebuilds. My HUP is a different story it still has only a mechanical fuel pump and if it is started every week regardless of temperature it starts fine, evens out and runs smooth quickly. If it sits for a month then it doesn't want to start and when it does it takes a long time to smooth out. I suspect that it is the all the stale gas being pulled out of the carb.
Another suspect for the rough running is the vacuum advance, is it working? Cheers Phil

Glad you like that little trick
Hi Guys
Wish I could say I thought of that little trick the first time I timed my HUP back in 1978. No such luck. I'll have to find the periscope timing light made up out of plumbing parts on 90EL, Y joint and a mirror sort of worked. Or the next version mirror taped to timing light. But it wasn't until I had the third or forth stovebolt engine on the test stand that I started to really get smart. But there is a further generation of thinking ahead, which I have done only on one engine, putting a TDC on the clutch housing and on the front pulley for each of the cylinders, this makes adjusting valves easier the one on the pulley lets you turn over the engine with the crank to the TDC for each cylinder to adjust the valve of course you still have to look at the valves to determine the valve closed position but if you remember the pairings you 1/6, 3/4, 5/2 it gets the job done quicker. Cheers Phil

Little Tricks...
Phil:
I would hate to think of what inventions you would come up with if you were in the medical field. That timing light and mirror might work on people for rear end examinations.....there would be no need for the examination table..... everything would be done standing up. Guy

You guys....
Resourcefulness and not knowing it can't be done are basic skills for working on a CMP.....
Phil You could write a book on "how to...for CMPs" .... and maybe you should.... That modification to the crankshaft pulley is genius and surely related to the old index wheels we used on V* for setting valve cycles accurately..... using a boxful of various offset keys...once marked every 120 degrees you are set for life.... I still think that using the inspection hatch on the bell housing for timing is worth it's weight in gold..... Now .... to the stale gas..... It seems to go bad faster than a few decades ago..... however the old gas form the 70s use to stink like hell.... new gas goes bad but you cannot readily detect the changes by smell alone.... I remember coming home after sucking gas from old cars in junk yards.... we used it to wash parts.... inevitably you always swallowed some..... my wife was always quick to point out my stinking breadth..... we stopped that practice after reading in a safety manual that only one drop in your lungs....once spread over the wet tissue like an oil slick... can suffocate you..... so now we suck beers.... It may be that Rob's gas had gone bad.... because his (marine mobile )tank stayed connected to his truck and when he went in the tent it had heated up and poured out when pressurised by sunshine...... it mayhave vented the best volatile components of the gasoline.... The other suspected thing is the dizzy was bumped and moved..... he did have two sparkplug wires knwoed off the dizzy,,,, and yes we checked the firing order... too young...too old..... just right..... perverts !!!! Vacuum seemed to be working when last checked. Next detective work willbe a systematic elemination process finishing with the timing...... On the electric fuel pump.... it has been a lively topic on Stove Bolt Chev site..... a lot of guys have been having problems with deteriorating gas line and in particular the fuel oumo diaphram..... some are advocating srtipping the pumping mechanism of the original fuel pump..... replace diaphram with a strong neoprene gasket.... removing the one way valve and using a hidden electric fuel pump to flow gasoline through the dummy pump to the carb.... it retains originality of the pump but is more dependable. I fully intend to install a permanent electric fuel pump on my cab 11 either in series with the mechanical pump or as a stand alone bypass system in case of unforeseen problems..... Please keep us informed of any other short cut you come up with while re-doing the HUP. Bob

Small World
I ran into my "Manitoba spy" at the airport today. While his progress report on potential border raiding opportunities was less than encouraging, he is still willing to conduct covert ops on my behalf. On the positive side, his list of potential SMP kidnap victims continues to grow...I hear that Winnipeg is nice in the fall. Just might have to find out.

Sparks Fly at the Barn
This morning started off a bit cold (-21oC with a wind-chill of -32oC), so Lucifer had to earn its keep today. While Lucifer warmed up, the doorways were shoveled and snow was removed from a few of the shelters. While this was going on, the frigid air was disturbed by the sound of an unfamiliar diesel engine. Gilles, from Cantly, brought one of his "small" trucks to the barn to give us a first hand look at one of his latest projects. After firing up the onboard generator (which came to life within seconds), the tour of the many storage spaces began. This truck will make any future MV convoys a little less challenging as it is kitted out with spares to beat the band. The tour of the truck included some tasty treats. No sooner had we opened the box of Tim Horton's doughnuts, Guy Vapeur showed up - I guess old habits die hard... Grant made his entrance and claimed the last treat and the group retired to the barn to bask in Lucifer's hellish glow.
The conversations ranged from various jokes, to sewing jobs and the S&P Rally to be held in July of this year. After chewing the fat for the best part of an hour, Guy parted company and the rest of us headed out for a bite to eat. Our newest favourite eatery is called Boboul, located in nearby Limoges. Hopefully this eatery will keep itself from burning down… Upon return to the barn, there were more jokes and kidding around. As usual, MLU was discussed in great detail. Eventually, we decided to do some work. The wood crib used to feed Lucifer needed filling. After shoveling out the back doors to the barn, we brought in some wood that we had cut and split last fall. Bob speculated that the load of wood should take us into the warm weather without resupply. Hopefully, he is right, but the cold weather we have been having in January does not auger well…It must be noted that we have had very little snow to date – both a good and bad thing. Good in that shelter maintenance and snow removal has been quite easy, bad because the lack of snow may impact the fire season in the late spring. There is still plenty of winter to come… After restocking Lucifer’s larder, Bob broke out his spot welder and with Grant’s help, we welded up a new set of hatch lips for the 45 and Prototype HUPs. In both cases, the original hatch lips had rusted to a state of non-repair. So, both sets of lips were ripped off and replacement lips got made up today. The new lips consist of two pieces of 18 ga metal. The first piece has a 90o bend that forms an “L” shape along its length. The long part of the “L” is about an inch and the other part is about ¼ of an inch. The second piece is just a long strip of one inch 1 and 1/4 inch flat 18 ga metal. The short side of the first piece was welded along the length of the second piece forming the necessary “lips” and mounting flanges for the large hatch opening. The lips of course engage the foam rubber seal on the sliding hatch thus keeping the rain and dust out. Bob and Grant were graceful enough to finish the last piece for me, as once again, time had expired. It was a nice, but cold day at the barn.

Photo 4-Destructive testing - Bob hammers the stuffing out of test sample of the lips Photo 5-Busted Lip...

Rough running engine
Try changing the capacitor in the distributor, a bad capacitor will allow the engine to start but will break down at higher RPM which can result in rough running.

Quiz Time / Feeding the Herd
Saturday reached the hellish temperature of 8 oC. There seems to be no middle ground with the weather this year. Too hot, too cold, too wet, too dry...we had it all this summer. At least we don't instantly break out into a sweat now.
Saturday was fairly quiet at the barn. Bob was away for his last swim of the year before the ice set in, and Grant was occupied elsewhere until about 3PM. My HUP restoration is now turning to wiring and ancillery part replacement. The attached photos show what I have been working on recently. Any ideas of what the first (photos one and two) and second items (photo three) may be? The panel is properly oriented in the second photo. The panel has a serious problem with rusting, so some metal work was required. After setting up the welder, I attempted to fill in a few holes. However, the wire refused to advance. A quick look inside the welder cabinet revealed why - the spool had emptied. It was not a good time to run out of 035 welding wire, but we have an order in for a replacement reel. Since the welder was out of wire, the rest of my day was spent painting the inside of the doors and playing with the HUP dash. I had planned on using a reasonably good shape deuce and a half speedo, but ran into problems with the end fittings of my speedo cable. So, the old speedo was cleaned up somewhat and installed. The numbers on the speedo face need some attention, but they are readable. I am now on the prowl for readable CMP gauge sets. The paint job on the doors was very messy. After removing the latch hardware, I opted to dump rust paint into the door interior and slop it back and forth to make sure all surfaces were covered. The doors were then left to drain of excess paint which will be re-used in the future. It was a good work out tumbling the 50 plus pound side and rear doors. In the future I will use the air gun as there is less waste. Grant made his appearance later in the afternoon. He is making good progress on his radio truck and when it hits the road, it probably will be one of the most accurate restorations around. Prior to leaving, a quick visit to the cat house was in order. For those who know Bob, you know I am talking about his cat condo that he built near his rear deck. It has heating lamps, blankets, feeding stations and a racoon proof entrance and exit. My job was to feed the wee beasties. After popping the lid of the first can of catfood, I became instantly popular with Bob's herd which appeared out of nowhere. They were most appreciative. Grant had cat slop duty on Sunday. With the chores completed I headed back to the city smelling slightly of fishy catfood. Oddly, the smell made me hungry... Photos: 1 - What is it? - in the 6" vice 2 - Same outside in it's proper orientation 3 - What are they (1" wide about 6" long 12ga metal)? 4 - HUP dash test fit 5 - Part of the herd
