rotary powered cart is waaaay cool
Only problem i can see is you want to make sure you have a very good air cleaner/filter on it.Any fine dust/grit etc. that gets through it will take the seals out of it quickly.Very nice design on the frame by the way.Wankels were used on 3-4 other brands too. I'm a vintage sled fan[atic] also.Arctic-cat,Skiroule,and a couple others used these engines too.The biggest problem was the noise and exhaust emissions in cars and motorcycles.Sleds weren't too closely regulated as far as noise and emissions back then.The reason the early sleds used a small carb was because these motors will turn 10,000 rpm.Be very careful to make sure you have some space around the exhaust/muffler areas.Temps on the exhaust on these are very high. I have not seen it,but i was told if the exhaust pipe is glowing cherry red the motor is running great!! These things will run very high rpm's,all day too.I have built several sled powered carts over the years and want to build at least one more,[i'm 54 yrs old].I'll see if i can dig up some pics of my old carts.
