Hi Floyd Kraft,
welcome to the BB.
The adjustment is 1 1/8" +- 3/64" from the bottom of the float chamber cover-without gasket- and the bottom face of the float.
As a rough guide the bottom of the float should be about parrallel with the cover face.
If you have the later carb with the horizontal main jet adjust screw, the screw works backwards due to a right angle belcrank in the little cover. This belcrank can get bent and you then cannot get the full range of mixture adjustment.
Screw IN to Richen, OUT to Lean.
The idle jet adjusts the amount of air mixing with the fuel so it also works back to front.
Hope this helps.
Cheers,
Eddie B.

Thanks, I will set that stuff in the morning, I also found out that the newer needles with a neoprene tip can cause a sticking problem since there is no fuel pump in the system. A friend said they had a lot of problems with that in the middle east on pipelines in the 80's and they found some solid brass ones in Belgium and seemed to cure the problem that I am having.

Happy New Year!
