Using the example of a homemade snowmobile, we will show how to modify the engine from a motor cultivator, increasing its power and at the same time spending very little money! It doesn't matter what kind of motor you have - it can be Sharmax, Lifan, loncin, Zongshen, Brait and other manufacturers. The principle of refinement for all these engines is the same - the installation of a DC CDI controller, which forms a dynamic ignition timing, and the replacement of the standard carburetor with a more technologically advanced PZ 30 (Keihin). Happy viewing!
