I have restored 4 of these tractors in the past 10-12 years. Just finished one a couple weeks ago. The parts are very expensive, new or used. Rusty Acre tractor parts is prolly the cheapest but have limited parts. Lots of parts on eBay but high priced. The engine is a Continential n62. The Pistons won't come out the top with the rod attached. The rod cap is larger than the Pistons. They are a pain to put new rings in. Here is the one I just finished.
