hi grumpy, i checked the valves again today and have the carby in pieces soaking. i had to spin the engine pretty fast to get a tingle off the spark plug lead, by then the piston was moving too fast to really tell where it was firing. one thing i did notice was watching the piston comming up on compression, there are two marks on the flywheel, one marked F and the other T, i thought firing and TDC, there is a cast line on the housing i presume these line up with. what is happening is the F mark lines up right on piston tdc and the T mark lines up after tdc and the piston is moving down about a quarter of an inch, if that cast mark does mean anything then the timing is not right, it seems the only that can vary is a sheared key. we have a few honda engines and i think to be sure its time to get a manual or diagram to sort it out, cause i'm really only guessing, does that sound like a plan, thanks micka
