Hi Grumpy, yes that is what I was talking about when referring to the timing, checking that the two marks on the camshaft sprocket lined up with the cylinder head surface, all lined up. With the carby I stripped it completely apart and blew it out with an air compressor. I have sent a couple of photos of the carby as well, could you tell me if this is the right one for this mower as it seems back to front compared to other carbys I have played with on Hondas. The compression seems to be fine as I have been told if you spin the motor backwards it will kick forward on compression stroke, which it will. Again is this true or not.[Linked Image]
