There was low power on this so I opened it up. Confusing was all the holes in the bore. There are about 7 holes. Theey are mostly on 1/2 of the bore arc and low so probalby intake and exhaust ports but weird there are so many. There are 2 small holes opposite and strange. One is low and one very high. What are the two small holes for?
The bore is smooth but I'm not just how bad the piston and rings are. The top had a fairly thick coating of carbon. Anything look obvious about the condition of the piston? There's blowby stain in the piston but I'm not sure if it indicates anything. The piston skirt is not scored.
