I did a search of stalling before writing this
After getting my 235' 1949 Suburban running and driving for about 2-weeks, it's starting to stall while driving.
It will bog out, then die; before that it was driving with no issues.after stalling, I can pretty much re-start and take off driving. It may or may not stall on the way home. Compression is good with all cylinders around 120-125. The plugs are white with the exception of #2 cylinder which is a little black. Power is a little low compared to my 250 cid 66' suburban. Climbing a small hill has to be done in 2nd

Kinda like it ran out of gas
It shouldn't I just had the tank cleaned
The glass bowl filter on the pump is full. Is it a suction problem | | | | | Joined: Feb 2015 Posts: 285 Shop Shark | | Shop Shark Joined: Feb 2015 Posts: 285 | A sticking needle or float, maybe...? | | | | | Joined: May 2005 Posts: 215 Shop Shark | | Shop Shark Joined: May 2005 Posts: 215 | Maybe
Carb is rebuilt so I hope not | | | | | Joined: Mar 2010 Posts: 10,270 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,270 | When I have a sporadic issue like yours, I just drive the truck until it either gets better, or gets worse. When it gets worse, it is easier to diagnose the cause. If it gets better, that means the gremlin found its way out by itself.

I may have found the issue
When trying to get the truck started, I swapped a newly rebuilt carter carb in for the original Rochester that was installed. During some trouble shooting and because of the lack of power I had my son floor the gas pedal (engine off) to verify the linkage travel and stroke of the carb linkage. Full travel on both and the carb hits the stop
But, when looking down the carb, it only opens a quarter inch, at best. After checking the original Rochester carb, full stroke when actuated by hand pretty much rotates the throttle plate 90 deg.
So I am thinking interference with the insulator? Since the original carb wasn't the problem with starting, I will put it back in tomorrow
Your thoughts?
Thanks Lou | | |
