hello I have a 1990 suzuki lt250s 4 wheeler and it needed a set of rings in it so i put some in and now i can't start it could the timing be off or what cause before i put the rings in i had to pull it with my van or another 4 wheeler to get it started then after it warmed up i could kick it to start but it was smoking so thats how i knew it needed a set of rings but i also noticed that the spark is real weak. just need a little help to get it going again. thanks suzuki rider
