I just received my new main adjusting screw for the carburetor on my H today and put it in. The needle is really tight to turn I can only do it with a screwdriver but I put it as close to 3 turns out as I could (hard to tell when it has slight resistance since it has resistance all the time both in and out) and it fired right up and sounded pretty good. Note: there was nothing wrong with tractor operation before this I just had a completely stripped and leaking packing nut.
I ran around a field with a disc real quick to warm it up and then went to do some fine tuning. However much to my surprise the screw does nothing to how it runs I can turn it all the way in or almost all the way out and the engine doesn't change....but it is running pretty good right now so maybe I'll just leave it just thought to see if anyone on here had an idea how that is even possible I would obviously like to be able to tune it better/open it up a little for plowing etc...
