    1974 Four Door Maverick with a 250 straight six(Now in that big junk yard in the sky), Currently a 1976 Mav with a I6 250 soon to have a 2bbl carb and dual exhaust, ooo yeah
    everything is bolted up and lowered into place. the problem is that it won't fire over, it wants to, but just won't.... Ive used starter fluid, and it won't just go for it. adjusted the timing, and won't.

    what are the proper timing setting for a 250? and what would it do if the timing was 180 degrees out?

    The car should start and run for sure with anywhere between 6 and 12 degrees of base timing. Get cylinder 1 to TDC on the compression stroke and then drop the distributor in so that the rotor points to cylinder 1 on the distributor cap. The car should start if everything else is in check.

    When I had my distributor 180 out, the car spit and sputtered and backfired through the carb. It would not start.

    Here's how I do it:

    Rotate crank to get #1 piston to timing mark on damper (check a Chilton's or other manual for timing specs) on the compression stroke. Install distributor with rotor pointing at #1 plug wire. Make sure plug wires are installed in right firing order. Pull #1 plug and ground against engine. Turn key on and rotate distributor body until the plug fires (may take a couple of tries to get a precise feel for the plug firing). Tighten down distributor clamp, reinstall plug and start car. Retime with timing light as necessary. This method usually gets the car running and the initial timing within a couple of degrees.
