Carb Help Please

Recommended Posts

Boney
Hello, With my 725 I am having trouble adjusting the carb. It does not want to idle. This is what i have done. -Warm it up, let it run about 5 min 3/4 throttle with choke on. If I try to close the choke it will shut itself off. - When I can run it at 3/4 throttle and choke off I try to lower the throttle to idle. When I do this it sputters and shuts off. - The exhaust really smells bad, like oil rich. I tried to turn the main jet clockwise to lean it out but it will shut off if I do it too much. The spark plug is black. - Any suggestions as to what I can do to get it to idle and overall run better ? Thnx for ANY help.
