Default Re: Lean MisFire

Hello Charlie ny,

Lets use the KISS principle here. LOL

I checked the wire on the Ford Load-a -Matic distributor, no shorting via Ohm meter and after running with a disconnected advance, same driving condition. I replaced the 52 jets with 49 as suggested and the driving condition was worse.

I believe I am fighting a lean carburetor condition in the Dennis Carpenter model 94 carbs. When I run larger jets the condition gets better but does not go away completely, and my spark plugs remain brownish. I have run jets drilled to 58 with better results in these carbs but still not a smooth drive under light throttle and a sustained speed wether its 10 mph or 20 or 30 mph. Once I am holding steady the bucking begins. The smaller the jets the worse the bucking/stumbling.

This all said. I want to purchase a points and condenser Chevy/8BA distributor from you Charlie ny that is set up for the 1950 239 flathead flathead with dual carbs. No Petronics for me please. :-)

Sincerely

Marc
