A reserve price is the minimum price the seller will accept. This price is hidden from bidders. To win, a bidder must have the highest bid and have met or exceeded the reserve price.
This engine was pulled from a Craftsman 42" lawn tractor. It runs great, no smoking, leaking or knocking. It has a 1" shaft approximately 3.5 " long. It is a Briggs model 422707 type 1254-01 code 9401115b cast iron sleeved v twin motor. I have no idea how many hours was on the mower.
