run bad but it run, lots of black smoke carb. is out of whack, what is the fuel mixture setting on a zennith all the way in all fuel, or would it be air,

 

[chrisinsoky]

black smoke tells me eaither too much fuel, or incorrect ign. timing right

 

[chrisinsoky]

alright 1/2 crank fires right up, seems to have more power then ever, everything good, except 1 problem the needle valve i was thinking that controls the idle air mixture is pulled out and in my hand, (i completely unscrewed it as the further out it came the better it run) where to even start carb rebuild?

try retarding or advancing along with carb adjusting that's what I did on a 841
