well so i had a look and the bore is polished like a very shiny coin with a mirror finish so i gave it a slight hone with a plastic makita abrasive disc and it sort of made it a bit dull with hone marks and gave a head a bit of a sand with some wet and dry on a very flat surface and it made no difference to the compression of about 95 still, and i gave it a few tugs fires but wont stay running so with the glazed bore and the amount of oil in the muffler i think she has done many many hours and is fucked basically i reckon a set of new rings and a bit more of a hone and she may run ok for sometime but i think she has done her time, so im gonna ask Ian how many hours he thinks its done im thinking now he most likely got it already used from someone else and ran it for a while before it failed to wanna run see he assumed it was the ignition but i have tested and checked and it has a very good spark.... im pointing to glazed bore not enough compression she has done her hours and needs a major job like hone and new rings or a rebore with larger piston, but i think parts are long gone for it unless i was to source a piston of the same size from somewhere else thats at the 63cc size but i think its possible but not worth the costs.
