My trike is idling VERY rich. I can see black smoke puffing out at idle. If you let it idle too long it stalls and the plug is all black. Once you take it for a ride, it cleans right out and runs good, until you let it idle again.
My question is: Do you turn the pilot screw IN or OUT to make it leaner?
P.S. Right now it's at the factory setting of 2 turns out from bottom. Is something else wrong if it's running rich at this setting?
