I've got a line on a FR3, in original running condition. Even the paint is original. I believe it's a 1959 model. What I haven't been able to find is how available are parts? Would I be buying something that is going to be hard to fix? Engine is from a saw mill and has a radiator, base and a clutch. I'm unsure if the clutch is a 1:1 ratio? I presently have a JKson 6/1 with a onan gen head. It was a jumper (big time), but eventually got it smoothed out with wheel weights. She's a good smooth runner now.... and I'm a happy camper!!
