I decided to have a quick look at the Kirby and thought I could give it a bit of a service, but it was that poorly looked after that it's now in a tear down stage. I don't think it had ever been serviced or cleaned, it had alot of carbon build up on the valves, piston and some light scoring on the bore. It actually cleaned up quiet well considering the condition it was in, so far I have lightly honned the cylinder and cleaned off some paint and rust. The only issues I'm having so far is trying to remove the valves, is there a trick to removing them, it looks like it's got a solid C clip. Also is there any info on valve clearance and ring end gap? going by the amount of carbon I would say the rings are worn. I can see why most people just replace the Kirby it's not as strait forward as a Briggs or Honda and parts and info isent easy to come by, what's the eqivilant model in the U.S just curious if I can get parts and how much.
