hello i recently purchased 5 husqvarna chainsaws for a 100$, 4 of the were 480s and the other is a 298xp. i have the cylinder for the 298 but no piston. i cant seem to find an afterarket one or even a good used one. my question is will a 2100 piston work in the 298 cylinder or can i simply put a whole 2100 top end on my 298. thanks for helping.
