[QUOTE="2strokesteve89, post: 221613, member: 1670"] Nice job on the aesthetics, so on the idle issue, does it run better on the choke? If it does it suggests what Mike said about it running lean is true. Try adjusting the air/fuel adjustment screw, basically with a warmed up engine run the screw in all the way (but don't crank the screw down, just lightly seat it) run it out about 1 1/2 turns, then start the motor and run the screw in until the engine stumbles, then start running the screw out untill it runs smooth and the idle doesn't improve anymore. If the carb doesn't adjust this way it suggests you have an air leak probably on the boot going to the engine, it may also mean you have dirty carburator passages that need cleaning. [/QUOTE]
