Yamaha didn't have a jet. I drilled it out two sizes over what it was with some tiny drills left over from my machine shop days. It runs great, started third kick without the choke. It has started first kick every time afterward. Now I have a slight problem. Gas running from the overflow (bottom tube coming off the bowl). I guess my float isn't set right. I was careful not to touch or mess with it and the needle. I'm taking the carb back off to have a look. Everything looked fine when I took it off before. =QUOTE] oh my. this is a joke, right?
