I havent used my 15 hp motor for 2 months althought it ran well when I last used and flushed it.Went to start it this weekend and it is frozen solid.I put penetrating oil in the cyl.and let it soak but still not free.Removed head and it appears that the head gasket was leaking into the upper cyl. and it there is some rust in there.Filled the cyl w/oil and it is sitting now.Any suggestions on freeing it?If it does free up,should I do a rebuild on it?It ran pretty well before and I'd sure hate to create more problems by getting into it.Thanks for any help.
