I've been going crazy with this 4 wheeler. It runs fine on choke, idles perfect , but want to stall when throttled. I've rebuilt the carb myself which didn't change anything, had my buddy clean the fuel tank and the carb just incase there was something I missed , that didin't help, brought it to a Suzuki certified mechanic who cleaned the carb, replaced the rings, adjusted the valve and checked the timing, he is now stumped with this bike.... says it must be electronic. Has anyone encountered anything like this ????please help "THE DOG"
