Disconnect the fuel line from the fuel pump to the carb AT the carb. Disconnect the coil wire. Have someone turn the ignition switch to spin the motor and see if fuel spurts out of the line. Be sure the fuel line isn't pointing toward the disconnected coil wire. If it squirts fuel, you're good to go. If not, you have a bad pump, or an obstruction. Pretty simple. Spdloader |

The lines in the center of the filter are the pass-through lines, the line off to the side is a vapor return. This line MUST be positioned so that it is at the top. Loosen the clamps and rotate the filter canister so that this line as positioned at 12:00. Your engine uses a mechanical fuel pump, I think. If so, have you made sure it works? I've not done a good job following your exploits under the hood, but it seems to me that you are spending an inordinate amount of time and effort on the fuel system.
