i have 96 zrt 800 just wandering how many turns the screw on side of carb is suppose to be out.when sled is running the center and mag cylinders and exhaust are heating up mor than the pto side could this just be bad plug or incorrect carb setting

Could be many things... start by switching the plugs around to see if one is better than the other. If this doesn't change anything, turn all of the screws in and back out to exactly 1 then start it up and turn it out 1/4 each time you start it to see what they need to be at.

right now they are all turned out like 5 turns from snug i just bought the sled i'm not sure where they are suppose to be

Start by cleaning the carbs!!!!! The air screw should start at about 1 turn out from lightly seated!

so it is set way to far out right know would that be getting to much fuel or to much air

Too much air, but clean everything before you start adjusting!

after i clean the carbs i should start at 1 turn out from lightly seated? it starts up and runs fine now with it out that far and is runni9ng cooler than other cylinders i thought it would run hotter with mor air going in.

Also get a spark tester and double check that you aren't loosing spark while it is running! That would be a sign of a weak stator!

You won't have the correct settings if you do it right now because the carbs run differently in cold weather but yes this is the general idea. 5 seems excessive... you sure it wasn't 2 1/5 and you counted double?

ok i feel a little stupid now i think i was playing with the throttle stop. if you were standing by your primary clutch the screw with the spring coming out is your throttle stop right? if so thats the one i was playin with.not used to this sled my other sleds where efi's and i never messed with it

I'm new to sledding, but a guy told me to let a 3 cyl. warm up for about 5 minutesbefore taking off so the left side (PTO) gets hot, this prevents eating up the plugs (fouling).

Go to the how too section to clean the Mics!

The pilot air jet screw takes a flat head screwdriver... on mine they face the right side of the sled, but I have roundslides. The other would take a phillips head.
