Nothing so far has got my any closer with a fuel pressure regulator. However... I lined the 0 mark up in the timing window and the rotor cap was pointed at #6. The correct order is 153624, right? Now do I need to turn my distributor 90° because of that?

The timing marks line up twice- - - - -once with #1 on the compression stroke, and again when #6 is there. You can set the timing either way. It takes TWO turns of the crankshaft to make the distributor turn once. Turn 1- - - -Intake/Compression stroke- - - - -turn #2- - - -Power/Exhaust stroke- - - - -"Rinse and Repeat!" The firing order is 1-5-3-6-2-4. If you turn the distributor housing 90 degrees, NONE of the cylinders will fire correctly.

Good luck, guys- - - - -I'm over and out!

Take no. 1 plug out and put your finger over the hole. Using a remote starter button crank the motor until you feel compression. Then rotate the motor by hand until the bb on the flywheel is at the pointer. I usually take all the plugs out and use the fan and belt to turn the motor. Once the bb lines up with the pointer, You are now at Tdc for cylinder no. 1. Trace the no 1 plug wire to the cap and put a vertical chalk mark right under the no.1 tower. Look at the octane selector plate and put it at 0 degrees. Take the cap off and look at your rotor. It should be pointing at your chalk mark. If it’s not, loosen the screw on the clamp, not the hold down bolt, and turn the distributor until the rotor is pointed at the chalk mark. Tighten the screw. Install your plugs and wires. Confirm the wires are in the correct firing order. You are now timed to fire at tdc.

Everything is timed right. This is maddening. The spark plugs I put in yesterday are already black and sooty from all the test fires. I'll try throwing the original carb back on, and checking the exhaust for obstruction. I'm just running out of things that could be bad. It just does not want to start.

You seemed to have changed everything that would make a difference. However, You said the truck sat for years outside, I would wonder if the exhaust my have been the home for some rodents. Take the muffler off and see if it makes a difference, Rats laove making homes in exhaust pipes and mufflers.

Not enough spark? I see a resistor wired in. 12 or 6 v coil being used? Use a 12v for sure and eliminate the resistor. See what happens. I dont use a resistor and my 261 runs fine. Food for thought.....

From the picture it looks like it has an electric fuel pump. I don't see a mechanical pump and the fuel line follows the heater hoses. What is the fuel pressure? There are only a few electric pumps sold now that produce carburetor level pressure. You have to look carefully at the catalog entries to find one that puts out low pressure. With either carburetor you may have to either replace the pump with one that puts our low pressure or buy a pressure regulator. I know that eight pounds will flood a pair of 228 Zeniths -- four pounds at all is fine. New reproduction mechanical pumps of any brand are a crapshoot.
