74 fj40 timing question (2 Viewers)

[nitroid13]

This is how I have my distributor set, I'm afraid that I have it a tooth off on the cam. 83 Fj60 dizzy and flywheel on a 1.5f don't really know if that makes too much of a difference

That looks to be in the general neighborhood , maybe a bit retarded. What i dislike about the 60 dizzy is how the hold down limits how far you can rotate the body.

I can’t tell in that blurry pic if your flywheel pointer is on the line or the BB. If you had the pointer on the bb instead of the TDC line, that would account for 7 degrees difference between your pic of the rotor, and the diagram.

One tooth off accounts for 27.69 degrees.
(360 divided by 13 teeth)

Here's mine. I'm running about 19*BTDC...

Those look identical to me save pig's junk is clean.

The position of the rotor doesn't have anything to do with how much advance it's set at. The rotating of the distributor housing sets the advance. It ok to have the rotor a tooth off as long as you can rotate the distributor housing to the desired advance.

It is at the TDC line

Ya kinda retarded like me lmao, so i guess its fitting. I can agree there... you can always grind off the slot and make a clamp that you can have full rotation. Mine is actually broke off lol. I need to fully grind the ears off and make a hold down much like the dui dizzys have.

Re-reading my post, I should clarify. Rotating the distributor shaft one tooth moves the rotor position 27.69 degrees. As pb4ugo pointed out, the timing is set by dizzy housing position.

Here is my other ignition set up that I'm using for testing purposes only lmao
