Well, maybe i'll do that on the next one. This one I remembered that I had a bunch of 4-40 nuts and just used them to extend out the arm. I then took a piece of glow fuel line and put it over the exposed part of the rod. This way it won't do any damage when and if it rubs against the fuel line. I just didn't want to risk having to buy a new carb for a new engine...you know?
