if you googlehow to set points on distributer the first answer is correct, with the cam lobe on the shaft opening the points it should open to 17 thousands
Assuming you have set the engine to #1 TDC and marked the position of the distributor and the position of the rotor, remove the distributor hold-down clamp and it's bolt, then pull the distributor up and out.
how to set timing on ford 1987 f-100 302 without timing light
The point gap is .017 inch / point dwell 26 - 30 / ignition timing 6 degrees BTDC / spark plug gap .035 inch / firing order 1 - 5 - 4 - 2 - 6 - 3 - 7 - 8 / distributor rotation COUNTERCLOCKWISE / according to motorcraft . com for a 1972 Ford truck with a 302 cubic inch V8 engine
There are two firing orders for the Ford 302. There is the standard 302 firing order of 1-5-4-2-6-3-7-8. Then there is the Ford 302 HO firing order which is 1-3-7-2-6-5-4-8. Make sure you are using the correct order. Set the #1 piston at top dead center (TDC) on the compression stroke. Now install the distributor so the rotor is pointed at the #1 plug connection on distributor cap.
I remove the distributor and rotate until the points are at the widest opening. Then using a .017mm fueler Gage I set the point gap. Reinstall the distributor, set timing and roll!
How do you set the timing on a 2300 mustang
Yes, when switching from a points distributor to an electronic distributor in a 1979 Ford F-250, you typically need to modify the wiring. This includes removing the points ignition components and potentially adding a power source for the electronic ignition module. Ensure that the wiring harness is compatible with the new distributor, and double-check for any necessary changes to the ignition coil, as electronic distributors often require a different coil than points systems.

set the plugs at .040 and all will be good.
To change points in a distributor, first, disconnect the battery to ensure safety. Remove the distributor cap to access the points, and then take out the old points by loosening the screws that hold them in place. Install the new points by aligning them properly and tightening the screws, ensuring the gap is set according to the manufacturer's specifications. Finally, reassemble the distributor cap and reconnect the battery.
A repair manual should say at what degree to time it. If you don't have a manual and you want to set it "by ear" do this: Slightly loosen the hold-down bolt on the distributor just enough so you can be able to rotate the distributor. Start the motor and let it warm up to normal operating temperature. Manually slowly rotate the distributor clockwise and/or counter clockwise until you get the best "purr" of the engine. Tighten the hold-down bolt.
i always had a meter with dwell on it you adj your points base and keep the gap the same Addition to above: Haven't messed with a points ignition in quite some time, but still have a Sun distributor machine and remember how to do it, if it's a dual point distributor the easiest way is to block one of the sets of points with a matchbook cover or thin piece of cardboard in between the points and set the dwell on the other set, then put the matchbook cover between the point set you just set the dwell on and set the dwell on the other set, then remove the matchbook cover and your done. If you're doing this on the car (as opposed to doing it on a distributor machine) you should then re-set or at least check the timing.
