I just picked one of these up from my neighbor that came installed in his Cermark Bobcat. I think it's only had a couple of tanks of fuel through it. I tried to do a search but the results were inconclusive. I was thinking about installing it on my World Models Clipped Wing Cub but would like some more information on it. I also have an old O.S. Max 40 BB that I could use but wanted to use the larger displacement engine. Any information would be appreciated.
