B dist.timing
 

Hey Guys,
Simple question I hope, but what's the difference between the rotor position when setting the timing between and A and completely stock B engine. Vince Falters site describes timing a B but with a Petrox (sp) setup rather than points. Centering the rotor on #1 dosen't work. Do I need to place the leading edge of the rotor on #1 like the A? I have the proper B camshaft pin hole. No luck on the thread search.
Thanks for your help,
Pete

With the pin in the cam gear and the + - set at 0, set as a model a with the points just beginning to open. The timing doesn't care where the rotor is pointing unless something is way off.

The rotor has to be placed opposite the number 1 contact. There are 4 lobes on the cam. Positioning the rotor opposite number one will get you to the correct lobe to adjust your points off of.

Thanks J,
I figured the cam in relation to the points was the key. I guess what threw me was the built in advance with the B timing pin hole. Not too much info. on the B's out there?

I did mine my ear and seat of the paints feel.
I did just buy some timing marks for the next time but it's been running great for 3 years now

I guess the proper way is to get it in the ball park then do the fine tuning with the + 0 scale on the side. Probably should try a timing light as well just for grins.
Thanks,
Pete

Hey Pete,,



If your using the B timming cover & dist,,,then you would just set the timming for a B engine.. just like setting the A timing



The 32 service bulletin's has the instruction's how to set it...The fine tuning is the bracket on the side of the dist.. + or -

Oddly, you started a thread on this issue last June with several replies. Click HERE to view. I addressed your particular issues within that thread but you can see it HERE. Now, if you can set your spark lever as described you have the option to time it as I explain on my web site:

Model 'A' Ignition Timing

Thanks Marco,
I think the confusion came from using an A dist. on a B engine. My question was the initial timing using a B dist. on a stock B engine. Today I set the points to break as the rotor meets the #1 cylinder. Seems to run OK.

If you have a B engine and want to run your old A dist. just put your A front cover on the B engine and all will work just like a stock A
