My car runs really well. Cold starts great. Has phenolic spacers etc but after I shut it off I have to have the throttles open at least half way and crank for 5-10 seconds to start. If I don't open the throttles then it will sound like timing is to advanced but clearly is not and it will stumble until it clears out.It has to be some excessive fuel getting down the throats somehow? What to check? Floats sticking?

Floats and fuel pressure are always good to verify.
What fuel are you running? I tend to have problems if I run the regular stuff at the pump that has ethanol in it. Ethanol free performs much better across the board in all of my cars/trucks that have carburetors. Harder to find and pretty spendy these days, but worth it in my mind for stuff that isn't my daily driver/commuter. |
