Ok, I have two identical sleds ... 2006 600 RMK's.
I have them both set up like this:
270 main jet
55 pilot
0.9 air jet
Needle @ 2nd clip from the top with the spacer inserts installed
One sled I have 1 full turn out on the air screw, one sled I have 1/2 a turn out on the air screw.
They are clutched identically, 54g weights, blk/red secondary spring, stock helix, stock green(?) primary spring.
Both sleds have brand new plugs, good fuel, etc.
Sled that is 1/2 a turn out on the air screw seems to cut out right off idle at low RPM, sled that is 1 turn out on the air screw seems to sing right along through the entire RPM range. Sled that is 1/2 a turn out does just fine at higher RPM ranges though.
My question is, can the air screw adjustment cause this cutting out condition? Or is the cutting out probably related more to an ignition issue?
I'm honestly not familiar with the 2 stroke carbs, I've messed with plenty of 4-stroke dirt bike carbs, but I'm not sure what the air screw adjustment does on the 2 stroke carbs.
