Retiring......
I was practicing retiring last Sunday....
Mounted 3 tires on my cleaned up rim using my home made tool....... First tire I buggered up the thread on the 3/4 in rods ...first of all I was mounting a used tire on a salvaged rim to be used only as a "Yard tire/rim" due to a missing stud. The rim had not been sandblasted and painted so more surface resistance. Anyways I destroyed all four 9 inch long 3/4 inch threaded rods...... thread had severe galling....also rod had no lubricant. Got new 3/4 grade 8 equivalent rod and new grade 8 nuts and rewelded everyting. This time I used never seize on the thread and the rims had been properly cleaned and painted slick black...... tires went on like a hot knife in butter...... used the brand new nuts from Australia...with lub..... waht a delight. ....and even had time to drive my rolling chassis around the back field...

Calling carburator gurus including Phil w.
Encountered a slight technical difficulty on SUnday while driving my C15a chassis.
AS you know Rob and I have had our stock Rochester B carburators rebuilt and flow tested by the Oak brothers in TO. Both our vehicles now run so ever much better...... and they look brand new. Well I was driving mine in the back field using just a fast idle setting when I decided to see if it would climb the steep...45 degree... pile of wood chip located in a corner of the back field. Amazing.... in low gear..low range 4x4 it went all the way up with out even hesitating or spinning...... did it a few times but chickened out going over the top has I had vision of possibly flipping over backwards and with no body/roof.... well I backed down. Did it again a few times and noticed that at a steep angle the carb was flowing raw gas ...literaly dripping gas...... not a good thing if all those fumes could collect inside the engine compartment......did not seem to affect engine performance... I raised my problem on the Stove bolt site and CarbKing confirmed that I may have exceeded the design of the civilian Rochester B carb which is intended for flat street driving. He even commented that the W-1 may have been better designed for such extreme military activity but defenitely too small for my 261 engine. He recommended sourcing a military carburator that would have been original on a GMC 270 engine. Phil have you had any similar experience with your new 261/Rochester combo? Does any one know what carb I should be looking for that fits a 270 GMC...? There is a possibility that a YF Carter ( carb ## ??) carb for a large 6 cylinder Jeep may fit the 261 CFM appetite..... the YF did have a special option for extreme tilt conditions experienced by CJ Jeeps in the 70s. Any suggestions...comments... besides staying on flat ground. Bob

Old memories......
This old friend of mine, which I had not seen in over 33 years found me thanks to my postings on MLU...... just can't hide.
Anyways Guy dropped by on Sunday and after a long walk through memory lane left me with a CD of old 4x4 club outings from the mid seventies..... man what a ride..... those were my Dodge years driving surplus M37 and M43. At the risk of embarrassing myself.... something I would never do.... I will post some of the pictures....stay tuned. In retrospect..... life as been pretty good...... Bob

Have not tried the 261 on 45 degree hill "yet"
Quote:
Interesting issue, maximum angle of operation for Rochester B Carb. First I'll have to do some checking in Chev parts book remember seeing that 261 engine was fitted in heavy 4x4 Chev trucks. I'll look to see if a different carb or float setting is listed. I have another NOS B Carb on the shelf I'll hook it up to the electric fuel pump and see what happens at various angles. Problem may be something stupid like that the current electric fuel pumps put out a little more pressure than the stock manual pumps as originally equipped. I'll check numbers but I think it is putting out 2-3 PSI more than needed. Did discover something that you may want to take into consideration if you are going to operate your 261 at extreme angle, keep an eye on the oil pressure. Discovered recently that my 261 at full song going down the highway is pumping so much oil up into the engine that if you hit the brakes going into a sweeping left hand turn the oil pressure will suddenly drop from 42 PSI to under 5 PSI momentarily. I have the 261 4x4 sump oil pan but it doesn't have the lower baffle found on the military 216. My surmise is that when you hit the brakes and turn left the oil sloshes forward away from the oil pickup allowing it to suck air for a moment. This doesn’t show up on the normal instrument panel gage which are slow reading due to their small tube size on my CMP with the standard 216 oil gage that reads 0-30 SI it is pegged almost all the time. I installed a second fast reading pressure gage which reads 0-80 PSI this one shows the pressure fluctuations. Got to do some more research on this issue. I have done some studies on what grade and side angles the original 216 systems could work at, I’ll have to put the pictures and notes together and post them.

Tell me more...
Hi Graeme....
Tell me more about this egocentric carb..... what model - year-application are we talking about...?? Strange thing about the Rochester....while leaking at that funny angle the engine never missed a beat amd kept running at the same RPM..... I would have expected it to flood or starve.... Bob C.

Side draft nightmares....
Alex
Those were SOB sidedraft carbs...... how does it compare to the Dodge carb Graeme is referring to...? Now you are going to tell me that all those Volvo carbs/cars that we sent to the junk dealer were priceless.... !!!! Bob
