My professionally built 331 came with The Edelborck #1806. The engine is 10 to 1 compression, edelbrock performer RPM heads, AIr Gap Intake and comp cams.
It started and idled fine before I did my first go cart. THen when I did my first go kart, I noticed that it would die when I stopped and also would not idle as well as it had. I replaced the elec choke hat cause I found that it was not releasing all the way, the new one has about 1/4 more travel. Then I followed the Edel instructions and adjusted the float drop and close adjustments as per their spec.
That go kart was 11 months ago and I now have the body on ready for paint. Same issues.
I am gonna check the fule pressure and purge the fuel just in case, I am crossing my fingers eyes and toes. WHo knows.
If I invest in a new carb it will probably be a Quick Fuel, as they are on the opposite end of the spectrum as the Edel, which has all bad reviews, and wherein the QF has all good reviews.
The Culprit !
