Air/fuel screw setting for skidoo

[skidoo50]

I have a 1997 Skidoo Summit 670 with the HAC system. Pulled the carbs and cleaned them and the air fuel screws were both different. Can anyone out ther in JD land tell me the correct # of turns? Thanks

typically 1 1/2 turns out to start with. Can be fine tuned from there. Normal range is 1/2 to 2 1/2 turns, beyond that the pilots should be changed.

Thanks, I did some surfing and found a pdf file on the sled. The book says 2 1/8 turns. I set them at 2, I'll see how it idles. Thanks again jimfsr
