I have a 98 suski quadrunner. I took the timing chain off to do some work and i am not sure how to put it back on. are there marking on them like truck engines? or is it just guess and check? and help would be great.

I would not recommend the guess and check method. I am not familiar with that engine but chances are it is an interference engine which means that if the cam is not timed properly the valves are going to run into the piston, which means bent valves when you try to start it at the very least. Get a manual would be my recommendation.

i did mark the what the timing was set at before but i wasn't sure if it would be ok to start from there, i was hoping that someone on this forum would know, maybe someone that knows is gone for the weekend though.
