I finaly got the new needles for my carbs. I went through them again all was clean no trash in the filters. I set both carbs with a pop off of 35 psi, the lows at 1-1/4, highs at 1/4 jets are stock (or at least what came with the ski). It runs strong, puls good, no rough spots, but is down 100 to 200 rpms from what it was with the old engine and it still looks lean on the wot plug chops. I am out to 1/2 turns on the mag and 1-1/4 on the pto highs. The ground electrode is witeish gray and the porcilin has a shiney metalic look to it the rim and metal portion still have a dark brown look to them. What am i missing? Fuel pressure? Do i need to change the high speed jets?
Thanks, Rod
