I am looking for what I think has to be a vacuum leak - hard starting and choke has no impact on running engine. Governor removed, ARC flywheel, performance air filter and exhaust, E tube and .036 jet. Once started after 15 pulls, idles and runs but closing choke has no effect on idle. The only changes this time are carb E tube and jet and flywheel. 32 degree advance wheel but using 4 degree timing key backwards to retard to 28 degrees since stock cam.
The only thing I see is the air passages on the head side of the carb - passages to outside air in both carb gasket surface and plastic spacer.Those passages are open to approx 1/8" ID hole/passage in carb base so outside air can feed to the passage in carb. This is all factory stock carb except E tube and jet. Are those passage to remain as is? I see nothing about blocking in any info on carb mods.
