Ok. So i replaced pamco knockoff that was fried, with boyer bransden micro with e advance. Tdc. Fired right up!!! Yay... But it was only firing on one cylinder. Took carbs apart and deep cleaned every nook and cranny. Carb cleaner comes out of everywhere the same on both with tube pointed at each hole, jet. Etc... Put back on bike. Still only firing on one cylinder. Switched plugs. Switched wires. Switched primary leads coming from e advance to coil. Put the old plugs back in. No change. It dies instantly on any throttle other than a slow slow twist. Sounds like sucking noise from left carb. Left cylinder is only one firing. Plug reads lean. Other plug still looks brand new. Now it will only pop on choke and then flip choke off and kick it and nothing. Flip choke back on and it will pop again. Battery was weak a bit. Have on trickle charge now. Boots are tight. No air leaks. No grinding or clacking when it was running.... Wtf
