TAIWAN QUALITY COPY OF THE ORIGINAL CARB FOR ( ATC70K0 _K1_1973+74) ST90 (S1215)
 
THIS HAS A 65 MAIN JET AND 35 IDLE JET

THE MAIN JETS HAVE A DIFFERENT THREAD PITCH THAN THE OEM CARBS DO,, SO YOU MUST BUY THE ONES LISTED HERE:  MAIN JET CORSE THREAD


THIS IS "NOT" THE SAME AS THE MAINLAND CHINA COPY THAT OTHERS ARE SELLING

MOST ALL OF THE PARTS FROM THIS CARB ,, OTHER THAN THE JETS,, WILL REPLACE THE OEM CARB'S PARTS (I TRIED THEM)

AND THE BLACK KNOBS DON'T FALL OFF LIKE THE CHEAP COPY'S DO

***(ON MOST CT90 MODELS YOU MAY NEED TO MODIFY THE OVERFLOW OUTLET TUBE/HOSE) SEE PIC ABOVE

Pull out the brass carb bowl drain nipple, cut off 5/16” and tap back into bowl leaving 3/16” stub to attach rubber drain hose. (thanks Greg F.)
