Dave, I'm having trouble ordering a part for my YS 45. Part number YS0215-45FS which is a head gasket. Mine is leaking and the local hobby shops don't seem to have this part listed.

Thanks Steve

Are you sure it's just the shim? If the head is warped or the top of the liner is messed up, the shim will not seal it. Bolt the head on without the shim, if it leaks you have another problem. If not, e-mail me your address at [email protected] and I will mail you a shim.
