If its cutting out when it gets to mid to high rpm's, you probly need to richen it up a little. usally when it wants to cut out at higher rpm's it is usally to lean. like everyone else said go ahead and replace the glow plug. here are the settings fron Novarossi.

If you are in trouble with your carburetor setting, this is a simple way to get back to the initial factory setting positions.


The High Speed Needle (A) is in charge to adjust the quantity of fuel necessary for the engine when the slide of the carburetor is full opened.
For a correct position, turn the needle-valve (clockwise) until it stops. It’s the fully closed position
(WARNING: do not force it to close it any futher, it will damage the needle!).

The High Speed Needle position is approximately 4.5 turns opened from the fully closed position.



The Low Speed Needle (B) situated on the throttle is in charge to adjust the fuel flow when the throttle valve is moving with the throttle servo.
The position of the Low Speed Needle must be flush with the housing.


The Idle screw (C) of your carburetor is used to adjust the air flow when the throttle is in the closed position (minimum RPM idle speed).

It must be turned to obtain a throttle setting of approximately 0.6 mm open once the throttle valve is closed


And remeber allways tune the high end needle first, when you have it set, then adjust the low end. after that if you need to retune for the weather the low is set and you should really only have to tune the high.
