Good advice, Jeff! I’ll keep that in mind when I finally get this resolved, THe only thing that’s bugging me now is the fact that when I hold the rotor and turn the dist case counterclockwise, the points are opening too soon.The limit screw was set when I used this engine for years without it changing, but now it has about 1/4″ to get to the stop. Something is not correct now. I’ve even gone thru the point adjustment again using the 1965 specs but it’s correct. Going to pursue the the 1966 specs and see if it comes out correctly. The confusing part is that I had always assumed, in the past, it was a 1965 900 and set it up accordingly. Never had any problems for years. Must be my advancing age giving me “The Stupids” !
Think I’ll have to take a break today since the long days of standing by the motor has stiffened up my back.

Dave, I have the the dist cap off and am putting the dist to the idle stop. I then put the rotor as much counter clockwise until it stops. Then I turn the dist housing slowly counter clockwise; holding the rotor in place, until point set 1 opens. This should be where I set the stop screw. The only problem I’m having is that that only travel I have is about 1/4″ from the idle stop position on the drive housing before the points open. When I used this engine years ago I could turn the dist quite a bit to the limit stop. Now it moves only the 1/4″ for idle before the points open. I didn’t measure it, but there must be at least 1/2″ to go to hit the max stop. The max stop is set where I had it in years past and ran perfectly. I know I’m missing something, just don’t know what at this point. I’m waiting until my die shows up Monday to clean up the threads on my .235 timing gauge and see how that goes. Right now I’m using a dial indicator. Haven’t worked on this motor for about 20 years and never had problems setting these at that time and it ran fine. Pretty sure I’m missing something.

I’ll take a look at that tomorrow, thanks Dave.
