Hello everyone !!! I am a snowmobile drag racer, but the winters here in SE Mich have been non-existant and there has been no ice. Tired of only being able to use the sled for only 2 months a year, I sold the drag sled and picked up a used ATV. I am new to atv's and will use it for trail riding with my sons.

It is a 1990 Warrior and it seems to run fine, but is hard to start when cold. What jetting should it have and how many turns out for the air screw?

Anything I should be aware of with this machine?

Thanks in advance for the help.
