Can someone tell me the dimensions of a 25cc and 30cc homelite piston? Diameter, overall height, wrist pin bore, etc. I am loking for a homelite piston, but don't know the size of the engine and info is not available (1982 homelite "waterbug")

Just go to small engines shops. They toss out complete weed whips ect. I give em a little money and that helps get more. Got 14 engines in last couple of weeks. Last one is a weed whip that had a broken drive cable. The engine starts and runs perfect. It had a 3/4 tank of gas in it too. Some engines had new parts in them also. Small shops in rural areas is good. Capt,n

Look into the exhaust port. If it has a bridge in the port, it's a 25cc. If it does not have the bridge, it's a 30cc.

25cc - 1.312
30cc - 1.437
If it's a stock homelite 25cc , it will have a bridge in the exhaust port . If it's been modded the bridge might have been removed .
