So this evening my neighbor (who is more mechanically inclined with a couple of porsche rebuilds to his name) and I spent 2 hours trying to get the 75 to fire. The PO had installed a new distributer with Pertronix ignition. The Prior PO had fitted a Weber Carb. First problem was that the timing was off, way off. Rotor was 45 degrees off. Got that reset by measuring tdc on one and going from there. Fuel is pumping to the carb. Compression seems good. Still won't fire. Hooked up the jumper cables to his GMC truck to make sure we had plenty of cranking amps and the most we ever got was some nice loud backfires through the muffler. How do I trouble shoot from here????
