Carburetor Repalce for ZAMA RB-K75 RBK75

When not working well: 1, oil circuit problem: fuel tank to carburetor oil supply is not smooth. Check whether the oil circuit is open, whether the tubing is choked or not, and whether there is foreign matter blocking.

2, the idle speed is too low: the new carburetor can not match the machine completely, and the old machine may need higher idle speed because of the aging or wearing of various parts. The new carburetor is based on a brand-new machine matching test, the test parameters are qualified after the factory, unable to meet the needs of each customer's different parameters. This situation needs to increase the idle speed: the valve screw at the red circle arrow (clockwise adjustment of 1-2 rings)

3, the negative pressure hole is blocked: the negative pressure hole is blocked also cause the extinguishing situation. Check whether the negative pressure hole in the red circle is blocked when it is installed.
