A mate's littl'un has a no-name (presumed Chinese) mini-moto, due to a surfeit of adult idiots thrashing it about at the Bulldog t'other weekend, it stopped, apparently seized... Luckily a bit of investigation revealed that the motor was OK (for Chinese values of OK), but a spring in the centrifugal clutch had broken up and was jamming between one of the shoes and the crankcase, but now I've been allocated the task of mending it... any ideas where I might find such a spring thing? It sounds like a chainsaw when it's running (apart from having a full-on expansion exhaust with no baffles, mwah ha ha), I'm guessing it may share parts with cheap no-name Chinese chainsaws? It has the same layout: pull starter, flywheel mag with integral fan, centrifugal clutch on the end, carb entering bottom (actually rear) of the crankcase with (guessing) a reed valve.

Why don't you put up a picture of aforesaid spring, alongside a ruler, so we have an idea of what sort of spring you want? I've got loads of odd springs from clutches and the like and might have something.
