Chainsaw Repair

That clutch drum fitted the clutch, crank and bearing perfectly and also fits the sprocket rims i bought, so my old saw lives again!! and has the option of 3/8" chain/sprocket!! win, win win!! 

Just wondering about the clutch springs....they are very tired, and i was wondering if the Stihl 090 springs would fit? they look very similar and the Stihl clutch body is a similar diameter as well, just a few mm difference, and i think that may be down to the clutch linings on the Stihl. The Alpina doesn't have any linings, just metal to metal (still seems to work though). If anyone could tell me the dimensions of the Stihl 090 springs (length and diameter) i would be very grateful also,

Many thanks "Again" for your patience and help....

Cheers Pete
