"I am running a recently rebui
"I am running a recently rebuilt (last week) solex 44 PAI carburetor on my AQ125a. I am using the stock high speed jet. I'm thinking the engine is running a bit too lean because it backfires every once in a while and my #1 cylinder plug was burned to a CRISP. Annode and Cathode were non-existent. Do any of you know what the optimal jet size is for the AQ125a engine IF it differs from that of stock? Has anyone encountered this problem?
I know it is not the spark timing, and not the wires. Also, max speed (37 mph) is reached at approx 4200 rpm at wide open throttle. I'm running a 14 x 19 prop.
Any help will be greatly appreciated!"
