Re: [FWDLK] AFB carb problem

[Bob Oswald <punch@xxxxxxxxxxx>]

Hi Nick.... with those symptoms  I'd be checking cylinder compression
before I messed with that carb, with my mind on the valve seats.    If you
had low compression then it would only be able to run well when the choke
enriched the mixture, then after it warms up low compression would prevent
continued combustion in one or more cylinders.  The black carbon could be
combustion gases blowing by the inlet valves and back into the carb,
further interfering with smooth running.

Subject: AFB carb problem

Hello Everyone,

My AFB carb is acting up again on my '58 DeSoto.  Before I take it apart
I was wondering if anyone else has experienced the following problem:
It will idle fine for about 15 minutes and then just sputter out and
stall.  I can usually start it right up again but it will run very
rough.  The choke plate and primaries are all full of black carbon.  The
next day the same pattern all over again.  I am assuming there is dirt
somewhere getting everything plugged up.  Any advice?  thanks, Nick Nichols
