Just upgraded to 70 cc, now JC Pinto is bogging down.

Mark Molloy /

Hello All!

Just upgraded my JC Penny Pinto from the original 50cc Puch e50 to 70cc. I did the swap and took it on a test drive. It runs fine at very low speeds but when I pull on the throttle the engine bogs down and stalls. Do I need to put a bigger jet on the carb? Pretty sure it has a 15mm Bing. Any advise is much appreciated.

Thanks

Mark
