Re: Model B Distributor in a Model A
How does one do that w/out breaking the rotor? I've never been able to figure that out.

Re: Model B Distributor in a Model A
JimZ, can we get a wider view of your timing pin location, like in the picture Charlie Posted?
I have seen those elongated bosses on commercial engines and have been told they were aftermarket, wondering if your timing gear cover is a "B" but without the elongated boss. Just a thought. Is the auto advance working in the distributor? |

Re: Model B Distributor in a Model A
According to Vince's site it looks like the Model A service replacement and all the
Model B timing covers had the elongated timing pin boss. The 1933-34 had just a round boss. http://www.fordgarage.com/pages/timingcovers.htm |

Re: Model B Distributor in a Model A
I’ll get a better photo in a little while. Even though the advance seems to be working fine, getting it timed per a proper procedure is unachievable. The best I can do is set it so it doesn’t backfire. I have no idea if I’m getting optimum performance. I’m thinking about putting a Model A distributor in it. Then I can enjoy the true Model A driving experience. I wonder if I’ll need to change the body or are the A and B bodies the same?

Have you tried a timing light? I have one that has a dial on the back that you can move to see where you are at. If you are running a 6v System simply power the 12V timing light with another battery. Of course you would have to get to TDC and put an indicator and mark on the crank pulley. NuRex makes a timing indicator. https://www.nurex.com/extra-crankshaft-degree-indicator Here is what I did. White dot on crank pulley is TDC, the yellow mark is 19 BTDC. |

Re: Model B Distributor in a Model A
Well my 35 year old $15 timing light won’t work. Funny, it was fine 20 years ago! Going shopping for a new one.

Re: Model B Distributor in a Model A
New $50 timing light shows that I had the timing set at exactly 19 deg. BTDC with my Model B distributor. I knew it was running ok but didn’t realize I could get 19 deg. by ear. Too bad I had to tear up the packaging to get the timing light out or I’d think about taking it back.

Re: Model B Distributor in a Model A
Static timing a B distributor isn't the best way to go...shoot for 1 degree advance per 100 rpm.. according to the math .255" on the circumference of the pulley is 5 degrees..so,at idle,or if you use a cheapie tach dwell,at 500 rpm is should advance a skossh over 1/4 inch...at 1000 rpm it should be hair over a half...3/4 at 1500,1 " at 2000 rpm..
