Re: The Model A Ignition System
I recently removed the upper plate to replace the wire and adjusted points/timing per Marco's page. I think the timing is too advanced - when I pull the spark control lever down past 1/2 way, the engine begins to misfire. I have re-timed it three times - with the same results. I'd like to loosen the cam and turn it ever so slightly to retard the timing and see if this makes a difference.
Make sure the wire pigtail is dressed properly, it can only go one way or it will intermittently short. Be very aware of the assembly hardware too, the wrong order can cause problems. |

Re: The Model A Ignition System
The distributor turns counter clockwise when the engine is running. Turn the cam clockwise to retard. This is what is called tweaking the timing. I had to do this sort of thing when I was struggling with the so called modern points.

Since this thread is 7 years old, you might get better response by starting a new thread. Be as descriptive as possible in your title. BTW, welcome to the barn!

Re: The Model A Ignition System
Turn the engine until the points are open, then turn the key on and see if the ammeter shows a draw. If it does, then there is a short to ground between the key and points.
If the armored cable is screwed more than a couple turns into the distributor, it can short to ground. The insulating washer must be under the condenser brass terminal screw head, or the screw will bottom out and spin the terminal, thus ruining it, or you'll have a poor connection and may not get good spark. |
