Hello to my fellow Beamer riders,
I restored a Honda 1981 Honda C70 a while back and I am having problems. I moved the bike to Albuquerque and installed a high altitude jet. The bike starts and idles well but under way at full throttle the bike surges. I tried a smaller jet and rebuilt the carb making sure all passages are clear. Set the points and readjusted the mixture 10 times all to no avail. The plug always is carboned up. I have a hotter plug on order.
I have no problem balancing my Bings but the little Jap carb has me besides myself. Most say carb problems are electrical. Condenser? Coil??
Any help appriciated.
