OK need help again. How do I determine where my pilot screw needs to be. The one on the inside of carb. I have it one turn out and my air fuel 1-1/2 turns out. I've teyed the needle in the 3+4th position. Its running rich and the air screw makes no difference. Can I turn the pilot in or out for any difference?

Well after further inspection I realized the pilot jet was screwed all the way way in. Backed it out lowerd the needle and now they work great. Was rather shocked with the throttle response

Carbs are gone idk how to delete post

What are they worth.? In fairly new conditions

I'd like to trade my 39 pkws for a smaller set of carbs I can run on a stock bore. Would like28pkws or stock. TThese carbs have 150 main 60 pilot dgh needle and 6 slide. I'm in Tennessee my number is 9314500496

I'll trade them

Thanks man I figured they had to be cause its getting way to much fuel.. Anyone want them lol???
