After complete disassembly and cleaning, I have rebuilt the Carburetor on 1988 TRX350D Foreman, and placed it back on the four wheeler. Cleaned the entire fuel system, tank, fuel shut off valve, new fuel filter, new spark plug. The Foreman had been sitting up for about 7 years, inside. Put new gasoline in the tank. Installed new Battery. Turned on switch. Control panel lights illuminated. Began short 2-3 second pulses on starter. After 8 or ten starting pulses, the old gal fired up and began to run at a much higher rpm than idle. Adjusting the Idle Adjustment Screw out did nothing and adjusting the Pilot Needle screw in or out did nothing.
I adjusted the timing of the throttle lever and slide piston keeping the butterfly closed while bending the metal tab to just contact when drum was moved. And I made this adjustment, on the bench, before attaching the throttle cable to the carburetor.
Thinking I got something wrong in carburetor.
Any Ideas? Thank you for your help. I am a novice. First time doing this.
