The cylinder balance test from GM calls for grounding 4 plugs and running engine on just two cylinders.....something I have yet to see.....

NOTE...engine was never rebuilt....but was a good running engine....as early as before Xmas it ran very smooth......

Stuck valve I believe would make different noise if stuck open.... not sure if we would hear anything if stuck closed....but if closed something would happen to the push rods..... may be it has....?

Is it possible....just maybe..... with the engine stored at -30C that some small amount of water could have frozen in one of the drilled out holes in the crankshaft...the ones they drill at the factory to balance the counter weights....... and we did not run the engine long enough to really get it to operating temp.... holes are about 1 1/4 inch wide...up to an inch deep.... if it held water frozen it might be enough to unbalance the engine....

Strange is the engine ran fine....vacuum was good.... picked up revs easy with no backfire..... but vibrated in a very low frequency rumble that picked up with higher revs.

Surely the combination of outside temperature just below freezing and the engine running would have melted any ice inside the engine? I didn't feel the oil pan temperature but if it got reasonably warm the rest of the engine can't have too far behind in the warmup - to my mind...

Bob..If it was a stuck valve you would get a racket from the push rod/lifter area..but anything is possible..bad gas..accelerator pump..did you do a compression test..??
That will tell you right away..Do a dry one and then squirt in a little motor oil (wet test) and that will tell you if it is a valve or a ring or could even be a piston skirt..
That would account for your balance thoughts..but a wet and dry compression test will tell you lots.
With out doing that first you are poking in the dark..
(If you need a compression testing gauge,I have one here kicking around some where ..you can borrow it)

One AA gun has been sold. One is being negotiated ($7500 per) leaving one available.

No metal gas cans

No good tires available but some 20 x11s remain.

Two 3/4 ton trailers at 400 each - were genny tlrs.

Two jeeps - civ Willis types dated 59 or so

Field telephones 15 each

Combat shirts and pants at 3 each.

Cylinder balance test.....compression test..... and yes I have a gauge...

Will also re check the plugs to see if one is not firing.... they were very black when we cleaned them up just before Xmas.... and running smooth at the time.....

When I think about it..... it is almost as if one cylinder was dragging... a dead weight........causing the engine to vibrate..... don't think it is a valve but will probably remove the valve cover..... look at it while running.... re-check valve adjustments.... verify all electrical connections.....

Above all will make sure it is warmed up sufficiently...... will cover the rad opening....

That would be your timing and bad gas probably..

Bob..Do your compression test first and it could be a plug or a thousand other things but at least a compression test will give you a general picture of the engine condition..
But a cracked or broken piston skirt is a possible culprit..
Take the valve cover off and roll it over on the starter to see if the push rods aren't changing hole..that will be a start too..and eliminate stuck valves..roll it over by hand with the plugs out when you are doing your compression test.

Road trip with the float on Saturday morning...... Rob should not have been let out with out supervision........

....and another local road trip tonite to recover an excellent 261 engine....

Will soon need another barn or more acreage....!!!

It's Jason's fault! He dangled photos of the HUP's naked frame in front of me, and that was it.

The HUP frame has some damage, but nothing that can't be repaired. Drive train and engine are intact (functioning? - not known yet). The four rims "look" to be in good nick, but time will tell. The frame also has a lot of the add-ons that are becoming increasingly rare in these parts. There is some sheet metal, but it has seen better days. So the HUP frame was a good buy in my estimate.

The other frame is a POS with only the two axles and some of the add-ons, making it somewhat worthwhile. There is potential for the frame and the other parts will go up for sale or be used as spares. The second frame (C15) came as part of the package deal worked out between Mr. Cote and myself. They are even going to load the trailer for us - on a Saturday no less!

The weather in Montreal was the shits. They have a lot more snow down than we do in Ottawa. I went through two jugs of windshield washer fluid on this trip due to the excessive slush on the roads and the resulting saltspray.

Not a bad recce - now I have to tell the wife about the latest acquisition...more on the the trip later.

Congrats, HUPs of any kind are a good find.

I too ended up making a purchase over the phone from prefair today, but pickup will wait until the spring.

That's an amazing store, I wish it was closer to here. Mind you, we have Westbourne, but the winter kind of limits purchases to only 6 months out of the year.

Rob..
Try to work in BBQ at Bobs..Last weekend in June..I think this year..Bob will be advertising it anyway..
It's a great do...
Gilles will be there again with his big field kitchen..and it is a great time.
