I saved this truck from rotting away in a field, about 2 years ago. 292 did not run, and I went through the whole routine to make it run...fuel tank, pump, lines, filter, carb, coil, points, condenser, cap, rotor, wires, valve adjustment, compression test (115-120), Pertronix igniter, repaired some rotted primary ignition wires. it went from running on 5 cylinders initially to starting and running very nicely. The problem is, after I drive it for anywhere between 1 and 5 miles, it starts to buck and stall. If I let it sit for 20 minutes or so, it starts and runs fine again. I replaced the points with Pertronix. still no love. I jumped the coil + side straight to the battery, suspecting the pink resistor wire might be bad. it ran, and didn't stall, but I just went around the block, fearing getting stuck again. I have tried to check the timing chain for slop, and the best I can tell without tearing it down is that it's fine. I have sprayed with carb cleaner looking for vacuum leaks and found none. 2 questions- 1) anyone have experience with distributor advance weights malfunctioning? 2) anyone have any experiences with the pink resistor wire and what happens when it goes bad?
