Carburettor Adjustment for a Beta 50rr

Model: Beta Beta 50
Part: Carburetor

Video tutorial

Today, we will give you some tips for adjusting the carburettor of a Beta 50rr. First, check the colour of the spark plug to determine if your carburettor setting is rich, lean, or correct. One way to adjust it is to act on the needle: remove the diaphragm spring, the diaphragm itself, and the conical needle.

Move the clip on the needle to adjust the carburettor, then reassemble the diaphragm and the conical needle. If that is not sufficient, adjust the screws on the carburettor, trying different settings until you find the desired adjustment.

Cheers!
