Question
well i asked u about my 49cc pocket rocket engine well i took the head off and shaved the piston head down to get out the scratches out and thenit fired i put my weed wacker carb on it and nothing will happen i tuned the idle needle to the same it was but were should i put the low speed needle    


and also i got a new one and i made a blower 4 it out of a playstation fan a steel tube and the stock air cleaner i hooked um the fan to the horn so wen i hit the button the blower turns on should i tune it to the blower or the stock tune

Answer
 Hello John:

 The Low Air Mixture Screw is Set so when Reving from Idle to Full Throttle there is No Hesitation. Tune it so you get Good Performance for the Function it is being Designed for. You May find that Tuning for Stock will Work Well with the Blower. The Tuning will be a Trial and Error Task Until you Find the Setting that Works Best. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome.

 Good Luck

 Respectfully

 John
