I've switched to a different engine and have two Rotax 277 free-air engines with gearboxes as surplus. The "primary" engine includes a carb and a Rotax exhaust. The "spare" engine is a bare block with gearbox. Both have recoil starters. The engines were rebored by Rainier Ultralight Engines and are running 0.20 over sized pistons. Crank seals have been replaced within the past 3 years. The grearboxes have both been rebuilt with new bearings, seals, and spring washers. one has a new main shaft installed by Lockwood. The "primary" engine has about 180 hours, the "spare" engine has 130 hours since new. Both of these engines were in regular service until late last year. With a spare engine and gearbox on hand, you can keep your plane in the air while you do maintenance on the bench on the other engine. It doesn't take long to switch out a 277.I'm asking $1,300 for the package but would split up if someone wanted only one of the engines. I've also listed them on Barnstormers.
