I'll try to help if you would like Gus. I have found that if you will turn the air mixture valve all the way in and back it out a full 2 1/2 truns this will give the engine enough air to run. And for the fule needle valve turn it in all the way and back it out 1 fill turn. This will let the mower start and run for a good time. you will have to fine adjust it from there. But this always works for me. Sour hope it works for you. Let me know how it goes?
