hello all, im gonna start off by saying that i already searched for the last hour or so and didnt find an answer...here we go basically i picked up an 02 shee about a week ago in non running conditon. this is my first atv first 2 stroke engine and first carb'd engine ever and i cant get it to turn over. i compression tested it and it only had 90 psi leaking down, so i tore the sucker apart and found out that it has 30 over wisecos in it and hot rods crank and rods...which was very pleasing to me!! got new piston rings and top end gasket set...bolted it back togeather last night and the only thing i could do is get it to backfire. compression is 120 now without even seating the rings, carbs are clean, reeds are in good condition, i have spark, i cleaned the leads on the stator....it seems as if the motor were out of time, but these things dont have timing do they???? i would really really appreciate if someone could help me figure this out, im supposed to go riding tomorrow and im trying to prove about 6 of my friends wrong!!! also they 4 or em are 660 and 700 raptor guys....so we gotta show em whos boss
