Rich/Lean symptoms

What are the symptoms of a G16 running lean or rich?

Thanks

They both stumble, lean at idle take off spits back. Rich will stumble all the way to wide open,l

Rich---lean is almost a carb linkage or dirty carb problem the factories are close on their settings.

I had a dirty carb and it was cleaned along with the pump and tank and the filter replaced. The mixture screw was turn in all they way then out 1 1/2 times It wants to stumble when I give it gas but then it revs up. Now it has been cold here <40 deg so it takes a long time to warm up. When it is warm it is not as bad. This was not a problem before it got dirty.

I also put a 6" jakes lift on it with 22x11x10 tires. Would the temps have any effect?

Start from scratch, CLEAN ever thing and go from there.

I have cleaned everything multiple times. It will be a while before I can do it again.

Cold temps can lean it out a little, give the idle mix an extra quarter turn out is what I often do. Make sure the airbox is sealed really well and it should run ok. If your clutches are dirty and not shifting well it can take off slower and not run as nice.
