Why would one do that?

Ok well this is better news. Clutch assembly and three springs fitted were OEM to rule out aftermarket quality. vibration would be :- needle bearing old/worn clutch drum old/worn sproket old/worn owt else?

Piston crown being the top surface? No indentations or dings. squish band? Piston ring? No dings just fused to piston at one point

Hi Twiggers. Could be interested. Wanna send a price over on a DM? Cheers

Clutch springs broke at the end of the coil. Also a tip of a shoe broke on one occasion! hardly use chainbrake unless on really sketchy ground so doubt it’s that.

Pretty weird. But no sign of something obvious?

That’s the thinking but I also want to not just scrap old saws.

what about scuffs on the side of the rod?

Yep sure of the misfuel but totally agree on pressure testing before going ahead. Looking at kits now....

Weirdly the gudgeon pin is worn with indentation of the needle bearing only on one side, the other is smooth. And I'm talking not laterally on the pin. ring location pin was gone allowing piston ring to rotate around and fused onto piston.

Cool I'll give it a measure but looks likely the pitting is the end of it. Yeah I bought the saw used not too long ago so the damage may have already been done... Thanks for help

Could be guilty 🙄

So is that the crank fooked and wanting replaced? that the cause of the woes? Wear on the side case is from when a clutch spring broke and a part of it jammed between clutch and side case. Know so as when I took it off to see what was up there it was jammed. Thanks for the caliper lesson 👍

Thanks for reply Adw, yep look like the locator pin has disappeared... So you think it's all down to shit aftermarket kit? Whats a good one that's not as pricey as OEM? or is it really OEM or go home?
