My T is now running great and bringing lots of pleasure. There is still one minor problem. I've learned to adjust the carburetor so that it runs smooth and starts easily. However, the adjustment won't hold. If there is a bump in the road or a hill, it has to be readjusted. Can someone tell me if tightening the brass nut will keep the needle in place? I hope that is the right terminology--still a novice.
Annette -- Yes, that is the function of the brass nut on the mixture adjustment needle. It doesn't take much tightening to make a big difference, so go slowly.
If it's one of these, a Holley NH, or one of the similar carbs, the answer is yes. It's called a clamp nut. Tighten it enough to keep the needle from jiggling out of adjustment but leave it loose enough for you to change the adjustment.
Annette, so glad to hear that you have your earlier T problems sorted out and that you are enjoying the hobby!
