There is a big snow storm coming and i finally got time to work on my sled. it doesnt run for some odd reason. I was feeling the piston valves inside the carbs and noticed that one was higher than the one in the other carb, even after i set both stop screws to 2 1/2 turns after first contact. I tried to turn the stop screw in all the way to see if i could feel the piston value go up but it didnt move. I then took the mixing chamber top off and adjusted it up which seemed to help a little bit but not enough to get the engine to fire. I really would like to know how to set the piston valve so i can get riding soon.

if you look at page 2 of this you can see the parts i am talking about.
