Is the screen still in place at the end of the fuel line where it enters the carb? If so that could be plugged up. That fuel filter must be able to be used for engines without a fuel pump (your B has gravity feed, which isn't strong enough to suck through the thick filter media). We put a clear plastic filter on our M. It ran really terrible and got worse with running time and load, the oil pressure dropped to 25 psi while idling with new 30W oil, and the temp gauge never moved past run while pulling the disk. When I saw steam out of the cap, I had an idea what was happening (it was VERY lean). Took off the filter and replaced the fuel line and the screens (also reset the timing, as it was a little off). Runs like a top, oil pressure is 55 or so at low idle, and thanks to a new temp gauge, it runs just under the run range unless worked hard. Also, I always clean the hole between the tank and the sediment bowl by blowing compressed air into the sediment bowl opening with the line removed and with the gas tank cap off. After draining the fuel system, it is normal (in my experience, anyway) for it to not refill immediately. Only the tractor with a small float bowl leak will refill immediately. Once it starts and runs a couple minutes, the sediment bowl or filter should be full.
