The Stovebolt Site Forums The Shop Area Engine Shop 1953 Chev 1/2 not idling

Hello All,

I got a 1953 rebuild Chev 1/2 ton and trailered the truck home (1100km). It run good when i checked it at the purchase location, but seemed to sputter when in higher engine speeds.

We dismantled the carburetor (Rochester BC, auto choke), cleaned all and got a rebuild kit. The engine idled before, but I feel the idle speed was set with the accelerator linkage, not with the idle screw.

Now we have no idle, but the truck runs on higher engine speeds, but not at idle.

The passages are all free and we are scratching our heads.

Any advise?

Cheers, Joerg
