Ok so I got the peice that broke on my engine fixed and now i'm trying to get the carb right. When I give it the full gas it seems to sputter and carry on until i close the choke flap. When i do that it takes off like a rocket for a while then it starts sputtering again then i have to wait a while before it will respond the same way. I'm assuming my adjustments are all out of whack. I have a seloc manual for it somewhere but i cant find it for the life of me. I know there is a high speed screw behind the drain screw for the bowl. Where should i set all my adjustment screws?
