When I quit the factory and ended up on free bread, I decided to build my own snowmobile.
Which engine to choose? From domestic selection is small: from the "Buran", "Taiga" or "Lynx" - nothing good. Imported ones are very expensive, and if you order delivery from abroad, then they will be delivered for a long time. And I also wanted newness - to install a 4-stroke engine, as recently leading world companies began to do. Then it will be possible to get rid of the main drawback - high fuel consumption. In addition, the 4-stroke engine has a higher torque at low speeds - that is what the utilitarian machine needs.
And why not use some stationary motor from a gas generator? They are reliable, the choice of models is wide. Leafing through the catalogs, he stopped at the 16-horsepower 480 cc V-engine of the American company Briggs and Stratton. It will seem to someone that the indicator of its maximum power is not very large, but the torque at low revs is not at all small (33 N.m at 2400 rpm) - another would be like that. The electric starter and the lubrication system - under pressure, scant fuel consumption, a two-year warranty - I chose it … When the engine was in my hands, it was possible to select the name of the car. He called it "Zimogor."
I took the frame and chassis base from Icarus. The engine was mounted on silent blocks from the VAZ-2108. I placed a sliding pulley on the output shaft, finalized the centrifugal regulator from Taiga. The pulley was machined under the increased belt travel (it is also from the Taiga), and the centrifugal gear was adjusted to a lower speed.
Made a new exhaust system - used a silencer from the Taiga. The carburetors removed control from the speed regulator and brought the cable from the gas lever. Glued the hood, provided it with a layer of noise insulation from the inside.
