I have adjusted the valves and know how to test compression on vehicles. Trick is the engine has auto decompress built into system run by a knock cam. Therefore I can't get pressure built up like normal as well as know if valves are leaking and in need of service. It is difficult to start at first. Has a constant velocity carb that is all rebuilt for millionth time trying to solve start problem. Has good spark. new battery. Book says hard starting caused by low compression. I just need to know how to perform proper compression test. Take out knock pin in cam? There is no manual decompress or kick start on this model.1994 DR 350 SL? Thank you!
