I set mine between 22-26 clicks… I believe that there are a total of 51 clicks.

Turn it all of the way in, then back out 22-26 clicks.

I’m not sure if this will solve your problem though.

Be sure that you don’t have the choke still on (i.e. push down the black button after you get it running).

Another thing to check… is the pump taking the fuel back to the tank working properly?  i.e. is the engine getting flooded at low RMPs as the fuel is not getting pumped back into the tank properly?

Hope this helps!
