optimisation carburateur "made by BA" + montage roulements sur l'axe

The carburetor was machined to accommodate bearings on the shaft, reducing wear and improving throttle operation.

Then, the internal settings were optimized to achieve a better airflow suited to the use of our 1/5 scale track and off-road engines.

The result is a more consistent engine, free from overheating, and therefore improved fuel economy.
