I just installed a hotseat speed kit on my 2002 400 explorer and now I have a sputter on the bottom end but once it takes off it is quite impressive.Does anyone know what I should be running for jets.I now have in a 200 main 35 pilot 1.5 turns out on air screw elevation 3000 ft. 65 F. Any input would be appreciated.

 

Try turning your air screw out another 1/2 to 1 turn out at 1/4 turn at a time and see if it clears up, if not, you may have to go with a leaner pilot.
