they decided not to do sh** and just look at it, they didn't even try and run it to the point of the problem they told me it was put together right but they had no ideas on what it could be. i told them i was going to change jets and they said that might work, well it didn't, i have ajusted the needle put a 120 jet in it and still the same problem, It's not a restriction problem as when it was stock it would do 42-43 now it cuts out about 38-40
