All Kolb Firestars came with wheelbarrow tires. The ones in the picture would be less drag and give a slightly faster cruise.

I have a chance to buy on I am also wond ering if the fan cooling shrouds and fan off a-Ski Doo-will fit an airc raft 377 or are they the same engine ?

Also, there is hole about 1.5" in diameter where a tube was connected to the shroud to deliver fresh cooling into the muffler on the sled. It would be relatively easy to rivet some sheet metal over this hole and then you could use the shroud on the UL engine. The fan and all the mounting holes in the castings are the same. The Ski-Do engine has the same internals, cylinders, and block as my UL engine but the PTO end of the block is not machined to accept a gearbox. It has the provision 8 bolt holes, which aren't tapped. I've read that this case can be machined to fit a gearbox, but of course it is verboten by Rotax. I'd be a little skeptical about running free air but you might get away with it. I see CHT of 350 degrees on climb out with fan cooled 377. I think you'd be pushing red line with free air. The other drawback to free air is that it cools down more during descent, so you have more risk of cold seizure. With fan cooling, the engine stays warmer on a rapid descent at idle, such as when doing touch and go practice. If you are careful about the way you fly it, you might be able to get away with it. The 377 has a reputation of running cooler than the other engines. Martin B. -------- There is something fascinating about science.
