I have been thinking about this for awhile now. 2 years ago I bought a Arco 3600 series at Windber it is mostly complete missing a few parts. I believe it uses the long chain cover. Not sure on what motor it takes. I know it should be a tecumseh. Seat is taken care of if this happens. The last raffle bike was a huge success. What are everyone's thoughts about another raffle bike for 2016. I will get pics posted of bike tomorrow.
