    I have read all of this thread, from front to back. Thank you Larry for all that you have given to this board.
    Went out to the garage today to look at my distributor that i had rebuild many moons ago, and lo and behold...It had the crane 99601-1 installed.
    I have the original dist. stamped 1112077, what is the total for this one?
    And as you can see form the photo below the cam adjuster is in the wrong place...

    Need to order new springs and take care of that adjuster. Not getting any vacuum at idle from the line that plugs to the advance. Stock engine with stock vacuum equipment. Ported line off the carb.

    That's a 1971 distributor,

    That is the way Crane instructions say to position the cam (adjuster). Not the best way. You'll need to remove it and drill and tap a hole and mount it. I have pictures on how to do it. Send an e mail to me (address in signature) and I will send them to you.

    That's what ported vacuum is, no vacuum at idle.

    Hi. Will be doing the power timing on a 67 340 4b Skylark. The distributor has been gone through, plate mod done and adjustable vac advance, dist# 1111159. Dumb question... Do I line up the 0 on the timing tape and 0 on the timing indicator before I drop in the distributor? Have already confirmed the 0 timing mark using a spark plug top dead center tool. Reason I ask is cause of this excerpt from manual. Thanks.

    Just because the marks are aligned does not guarantee that you are on the compression stroke. The marks align on the exhaust stroke as well. To make sure you are on the compression stroke, remove the #1 spark plug and cover the hole with your finger. Have someone bump the starter a little at a time. When the piston comes up on the compression stroke air will push your finger off the hole. At that point, the mark should be coming around under the water pump. Continue turning the crank clockwise until the Mark aligns with the 0 of the timing tab. Install the distributor with the rotor tip pointing at the #1 tower of the distributor cap. Make sure you fully seat the distributor into the timing cover and the oil pump is fully engaged. Install the hold down and bolt and tighten it just enough so you can just turn the distributor by hand. This is very important. If the hold down is not tightened down, the distributor can pop up when the engine starts and disengage from the oil pump. Good luck.

    Thanks for clarifying that and the rotor pointing at 1 on the cap. Have a few things to do yet, July 4th I will have a helper available for timing.
    Thanks for keeping this thread going, read all 41 pages.
