sled ran two years ago but was often hard to start.....started working on it yesterday. Looks like an oily mess over near the injection pump and the oil pump lever has fallen off. The engine is now somewhat removed and looking for a source of the oily mess but it's really hard to tell. Does the injection pump lever get loose and fall off?n I think maybe carb was loose and my son tightened it down so I was worried about a damaged cylinder wall. I checked compression and the single cylinder has 105 psi comression with a spark plug type gauge. I still could not get it to fire on ether which makes me question timing at this point. Not sure really where to start, hope to get oil pump lever hooked back up. Any thoughts on this? thanks, moday
