Re: Which way to move stop on needle valve to lean out mixture?
started to run 4 ounces of quality 2-stroke oil (NOT the family dollar store weedwacker crap) after second tank of fuel. this is about 32:1 and seems perfect. these motors are pretty understressed. clip down for rich, up towards top for lean on the main jet needle. try NGK B5HS in place of the chinese stock plug. looking for dark brown to tannish color on center porcelain electrode area. white bad/lean and black bad/rich. hope this helps
