As I'm using my 955 more and more lately and getting comfortable with it, I'm starting to push it more and work it hard. I've noticed that there is what seems to me to be way too much blow-by gasses coming out of the breather tube. I have no history of the engine, how it was used, how it was cared for, or how many hours are on it. All I know it that the engine sat for a few years without being used. I've ordered a compression tester and will check the compression when it gets here. Based on what the test yeilds, I may be looking at a partial overhaul this winter. Might just be worn rings or it might need to be bored. Could also be valve related... just won't know until I get into it. If I have to get into it, I'll have the head, valves, valve guides and valve seats checked out as well.
Right now, the engine still starts easily and has no noticeable power drop off when worked. I've dug out and moved about 70 yards of dirt in about 12 hours of use. A friend of mine thinks that a compression test at this time may be premature and says that the excess blow-by gas may be a result of the engine sitting for an extended period and that rings my free up or reseat after some use. That would be nice, but I'm not too hopeful.
