help with centrifugal clutch

[SilkyKameron]

i have aquired a gokart frame with steering column and engine (already mounted and aligned) for £20 and i am having bother with the clutch, on account that its in peices

anyway let me start by saying i dont know what hp it is but here is wat the serial sticker says:

05R080115

and actually stamped into the engine is the following: (i think)

05R080115

the thing is the person who i bought this off says he crashed into a lamp post and the metal casing that slips on the crank shaft with the sprocket attached CAME OFF, and the 6 peices that were inside were lost. clutch dogs i think they are called anyway 2 were found. i have the casing with the sprocket attached and the other bit that has a kind of spring wrapped round.

the crank shaft is odd i think because i dont seem to be able to find a new clutch anywhere.

the crankshaft measurement is 19ml inside the crankshaft and outside is 22ml

the centre of the clutch peice with sprocket attached is 22ml which tells me that it sits perfectly on the crank shaft.

the sprocket has 10 teeth

im thinkin about takin the leftover peices off the crankshaft but aaaaaagggggghhhhhhh

what engine do i have from the measurements and description given above and where do i get the parts from.

yours sincerely

Sounds like when he crashed into the pole the rotational mass was enough to rip off the CB (Clutch bell). And now a new clutch wont fit because it may have knicked/burred the shaft. Take some measurements with a caliper and polish up the shaft with some fine emory paper and then measure it again in a few locations down the crankshaft and check for consistant measurments.

the dogs are the clutch shoes for us across the pond. if you can't find a used one to cannabalize you will have to buy new. at least thats how it is for me. ml? milimeters? check for burrs and have a conversion calc available then go to comet clutches with your measurements. happy hunting cheerio!
