Ok, compression on my 200es is so low, it won't start. If I put my finger over the spark plug hole and crank the engine, no air leaks around my finger. I can feel the compression, but not very much. I cleaned the carb, tested for spark, fresh gas, so next thing is to take off the head and inspect the valves, cylinder, and piston. I'm probably going to have the cylinder bored, get a new oversized piston, and new valves. Anyone here have any suggestions on where to get the piston, rings, and valves? How about valve seats? I saw in the shop manual that I have (the one from Honda) that tells you how to cut the seals...but is there anywhere that sells them ready to install?
