i got done ajusting my valves on my 200cc atv becasue it would not start before. so i got done ajusting them and cleaned the carb all out and then put everything back on and have the 2 carb screws about 2 turns out. so i took it up the road and it ran good until then it died and would not restart. it would atempt to start then just die. so i turned the air screw(one at the bottem) about another 3/4 turn out. it started up and ran fine. then after like 5 mins it started to turn on then off then on. it didnt die yet. so i tred to get home and then it popped real loud. i let it sit for about 5 mins and it started up and took me home then started acting up again. should i maybe turn the air screw in more instead of out maybe? thanks
