My YS53 bit the dust today. It must have ingested something as the rotary valve, piston and cylinder are all heavily scored. It was running really well even after I fixed the hole in the carb and heavily modified the intact tract with JB weld to smooth the flow of air into the crankcase. That repair looks as good as the day I put it back in service. I ran almost a gallon of fuel through it before today's failure.

So to my question... Does anybody out there have a 63 or 70 laying around they might be willing to part with? If a choice can be made a 70 would be prefered as it is a bit newer. Nothing in the for sale section here.

Thank you.
