If the resistance was really off on your TPS, it might have been causing the igniter to select an advance curve that didn't exist. I don't like the idea that the make you buy a new carb to replace it. It might be interesting to work out the resistance range on the TPS and replace it with a variable resistance mounted through the clock setter hole on the dash. There might be some times when manual advance curve selection would be useful.
As for making the engine run faster, first step would be to redo the ignition system. A different coil design or a mod to allow independant timing on each cylinder would be needed. This might be possible with 2 T100 igniters fired by 2 crank position sensors. Of course, the trigger tabs on the alternator rotor would have to be modified. Either a single tab like the 360 engine with the second sensor mounted 90 degrees around the rotor or the sensors side by side and the tabs modified to trip only the correct sensor.
