working on friends bayou 300 4x4. when it first started, if you turned on lights it would die. eventually would not run. he removed all wiring, no bare spots, or broken wires. Then new cdi and regulator. by this time it had sat up for a year. would not crank. took carb off cleaned good, removed all jets, blew through all with carb cleaner 3 times, 3cans carb cleaner. now it will idle, but dies when you give it gas. timing looks right, valves adjusted correctly. any ideas? I am at the end of my rope with this thing.[&:][:@][:'(][sm=chairshot.gif]

 

I beleive it might be in the wiring, should the black wire with yellow stripe coming out of cditie in to lights?
