Distributor rotor

[LEM]

The attached picture shows the relationship of my rotor and distributor body Number one insert at top dead center. Looks like the location is too far past center of the insert. Is the Timing gear off location?

Hmmm looks spot on to me, if your spark lever is in the full retard position. Do you have any backlash in the distributor drive setup? Meaning, can you twist the rotor back and forth and if so, how much? With all backlash removed in the clockwise position, the rotor should point to the contact just as shown in your picture. If you can twist it clockwise past the position shown in your picture, the timing will be too retarded.

Looks good to me

That's the way I see it.

That is dead on perfect.

While you are at it, you should check the space between each post to the end of the rotor. Should be about .025. Every time you change a rotor or dist cap the gap will change. You will either file the post or bend the tab, depending.

When I tried bending the tab on the rotor the rotor broke, since then I just check that all 4 contacts have enough clearance and leave it like that. Having different gaps between the rotor and the distributor body contacts doesn't seem to affect the running of it none.

Thanks very much for everyone that had their input. I am now confident that everything’s OK thank you again.

Jay, Many of my friends who put their trust in god came home in body bags.

Maybe the OP thought it rotated the other way? Might explain his confusion.
