I have two air cooled Petteroids for sale. Both are brand new old stock, test run only. One is the standard size the other is a mini. HP ( I Think) iis 3.5 for the mini and around 6.5 for the bigger one. Both are fixed speed 1500 RPM. Both start easily and run nice. and have a v belt pully on the cam shaft. Mini is complete in every way, big one is missing air cleaner and original starting handle but I made up a handle that looks and works great. An air cleaner can be fabbed up for addditonal $$ I will post pictures and have the actual HP ratings later. I have inspected the internals and they are clean and well made inside. They have been test run, flushed and filled with Rotellla oil I would like $550 for the mini and $750 for the other. $1100 for both and I am open to interesting engine trades.. They are in central Ohio and I would preferr to not have to mess with shipping but if buyer is willing to pay me to crate I will consider it. Please email or PM me if you have interest in these
