the carb? At the moment it only runs with the choke fully on. I've taken the carb apart and cleaned it and everything there is fine. I'd just like to know the settings for the carb, in particular how many turns in or out for the mixture adjustment screw. Hope someone can help!
 
Choppy has it about right for the pilot mixture screw. To narrow it down, get your idle where you want it. Turn the screw in until the idle drops, counting the turns. then turn the screw out to where the idle drops, again counting the turns. set the mixture screw halfway between those two points. If for some reason the carb needle has been out of the slide, set the clip at the middle position (assuming you havean adjustable needle).
 
rule of thumb for any carb: turn the mixture screw in untill lightly seated and then back it out 1 and a quarter to one and a half turns and then set your idle speed.
