OK, so. Swing and a miss and possible a new direction. I went out and was going to open up the distributor and in the process realized that the bolt in the bracket that holds the distributor had come out. I thought for sure I was on to something (picture below). Went to town for a bolt and put it back in, but as I was putting on, realized that the distributor would still be in the same relation to the rotor, so doubted it. It did fire right up though and seem to be working. It definitely works better cold or with a fresh battery. I started down the road and it runs decent, then starts to miss again. As the tractor warms up, it definitely gets worse. I am beginning to think it may be a fuel problem. While it is sitting at moderate idle, I can definitely see the governor calling for the carb as the engine misses and begins to slow down. The governor seems to call for the gas fine. As it calls for the gas, it just does not seem to pick up. It also doesnt seem like it is flooding. it just seems like the fuel flow stops and the cylinders quit firing suddenly and the engine coasts down. It seems that as the engine warms up, the fuel does not flow. I'm still struggling. So as I am sitting here typing this, I'm wondering about the valves...right? Help me out here, but proper seating of the valves is what creates the suction for the fuel to flow...right? And the fact that it seems like it rotates freely after it starts to die might also point me there? Am I on the right path and if so, is there a cheap fix here? SeaFoam or other solvent to get the valves to seat better? Also, could it be air leaking around the manifold after the carb?
