1927 10-20

Bob Kerr · Jul 16, 2016

Just picked up a 27 10-20 yesterday. Pretty good shape but sat outside the past few years. Guy said it didn't run right after he took off the Dixie Mag. Sold all my 10-20 books when I sold my last 10-20. Bolts are not 180 degrees apart on the coupler. Should they be on the Dixies? I know they were on the E4A mags. I have a feeling he just put the bolts in where he could get them to go.

I never go by the bolt position, go by the book and you can't go wrong.
Line up the top dead center, fully retard the mag and line up the coupling
holes with the mag on #1 and the points just beginning to open.
Most times i pull the valve cover and watch the #1 intake valve, open the side hand hole
to know for sure #1 is up and then trun till the tdc mark is lined up.
Years ago i studied the manual real well as i didn't want a kicker.

I studied the book too, but that was years ago and this is a differnt mag. I was thinking the two coupler pieces only work with what mag you have whether Dixie, E4A, F-4 to make sure they go in the right position. Not sure if I remember that all right.

The timing ring should have 2 bolts directly opposite of each other regardless of which mag it is. With the engine set at TDC and the mag set to #1, only one pair of holes opposite of each other should align. Somebody forced something.
