Re: Intake manifold getting hot
I didn't say that where the rotor tip points controls when the points open !!! I said that where the rotor tip points is where the spark goes . Adjustment of the distributor cam controls where the rotor tip points . The spark happens when the points open . Of course the lobes of the distributor cam controls when the points open . Where the rotor tip points is the most important thing about ignition timing . When the points begin to open is when the spark occurs . These two things control how accurate the initial , ignition timing will end up . If the rotor tip isn't pretty close to the proper position the engine won't run . It is often a waste of time trying to explain a procedure to a person that is more interested in argument than anything else . .

I guess this the point I am trying to make: By following Ford's procedure the initial timing will be correct and the rotor tip position will take care of itself. |

Re: Intake manifold getting hot
Here's the update, points were at 19...that don't matter.
Timing dead on. Steering column shifted...bingo

Re: Intake manifold getting hot
When you say steering column shifted, do you mean the spark advance lever was set incorrectly?

Re: Intake manifold getting hot
Burner31, When you rebuilt your distributor, did you put in a new points cam? If so check the finish of the cam. I rebuilt a distributor a couple of years ago w/a new points cam. I didn't inspect the cam, I just expected it to be good, and it wasn't. It didn't take long for it to wear down the rubbing block on the points causing running problems. I found the finish on the new points cam was quite rough and ended up smoothing it out w/crocus cloth to a glass like surface. I also had to replace the point arm as the rubbing block was worn down past usable.

And yes the the column shifted causing the advance arm to not advance the spark enough, so got that realigned and reset the points, seems to run better, was hoping to drive it today but now it's raining...again. I cleaned/lubed the cam when I did all this but did not inspect it per say, don't feel like going out into the cold garage today so will wait for a dry day and drive it, see how it is and check the cam next time I break into the distributor again. Thank you all for your comments and advice...you are all more like Family then Family (Only my wife has support and interest in my Model A)

Re: Intake manifold getting hot
Be extremely frugal with any type of grease you put on the cam. A little too much will get thrown off and can soil the points.
