OK. Any thoughts would be appreciated. Have a Ford 3400. I had the head rebuilt after the engine got "drowned" during a heavy rain. Installed the new head, new points, coil, etc. Here's my problem. After going through about a hundred times of regapping points, plugs and bypassing resistor wires, I decided to replace the points with a EI Pertronix distributor system. I have plenty of spark to the plugs but still it won't start. I've removed the carburator and squirted starting fluid direcly into the intake manifold to see if a spark would happen. Cylinder compression is between 70-75 for each cylinder. I've have suction at the intake manifold, and pressure at the exhaust manifold. I do have a slight pressure at the oil dipstick. Any thoughts of what to try next?
