Everything you need to know about adjusting your carb can be found in a Haynes manual. Thats really the best way to go about it. Go at it step by step, there are a lot of steps, but each one is easy. Actually, everything with the 22r carb is pretty simple when broken down, looking at it as a whole is intimidating. I dont know why you would need to re jet it, unless you have a very built motor? What ever you do dont give up and get a weber. Good luck.
