funny you ask about the jets. I figured that I would have to jet up, so I went from 300's to 370 just to be safe, ran like hairy ass dingleberries. Worked my way down to 330 and still the same. After about 9 hours of cutting away at the air box and the mounts to make jetting easier on me I just put it back to where it was and that was at 300 and took the pilots to 30 and moved needle one clip towards lean. Ran a lot better but I am still super rich, I fould plugs every 3rd right or so. I am gonna try a 290 when it warms up because now that it is a little cooler here in Orlando (40-50 farenheit) it has been running great and the plugs are lasting. The only thing about jetting is that you have to start somewhat high and work your way from there, there is really no way to be able to say what because every motor is different. I have about 50 dollars in jets that I bought and cant even use:(.
so back to the original question, I had to actually jet down
