The distributor is moved to adjust the points (rather than turning the engine to get to the high point on the lobe) then the distributor is returned to the original position by lining up the 'pointer'; I thought it was on Stovebolt but I can't seem to find it. Has anyone heard of this tip and where it can be found? Thanks

It's a small world, but I wouldn't want to paint it.

[I can't speak for earlier engines] When my timing is set up right, with the distributor cap off, the Rotor points to the No. 1 cylinder when the engine is at top dead center.
Every 25 years I like to rebuild that 292 just for GP

The octane selector is the marked thing on the distributor boss. Loosen the cap screw to where you can turn the distributor to where you are on top of the lobe. After you install the points, return the octane selector back to where it was in the beginning. | | | | | Joined: Aug 2008 Posts: 116 Shop Shark | | Shop Shark Joined: Aug 2008 Posts: 116 | Speaking of the octane selector...I've been pondering on that thing for a day or two. Isn't it really a means for setting maximum distributor advance? I mean, if the base timing is on zero (the pointer is pointing to the ball), and your octane selector is also on zero, then you have about 5 or 6 degrees of advance available to the distributor when you accelerate. If you move your octane selector from this base, you either increase or decrease the amount of advance (and therefore power) available to the engine...I'm askin' here...not tellin'...any other explanations?

I think it was originally used to allow easy advance or retard adjustments (and return to "mark") due to varying grades of gasoline and or for travelling at different altitudes?
