1275 firing order and plug wire arrangement

[TulsaFred]

Trying to place my dizzy and set static timing.
I have a side entry distributor cap with two "low" posts and two "high" posts.
I believe the firing order is 1-3-4-2
At TDC of cyl 1 the rotor is pointing to approximately 2 O'clock, which corresponds to a "low" post.
If the rotor turns clockwise the next post is a " high" post which I assume goes to number 3 cyl, then another "high" post to cyl 4, and finally the last "low" post to cyl 2.

Does this sound correct?

don't know about the posts but it is indeed 1324.

1-3-4-2 you mean, I think!

Yes, Roger is correct.

1-3-4-2

That's common in most four cylinder engines from Honda to MG to Chevy.

When running (in the car), the distributor rotor turns counter-clockwise.

The picture below (not mine) may help.

One notable exception being 4-pot Fords which were 1-2-4-3. One odd curiosity is the Lotus-Ford Twin-cam. The engine block on which it's built is the Ford Cortina 1500 engine, with 1-2-4-3 firing order, but Lotus modified it to the more normal 1-3-4-2.
