hello Kevin
I had the same symptoms and I found the primary wire was not seated all the way into the coil. The coil wire and its end terminal were a tad to large and it wasn't seating all the way in, after I tapped it in it solved my problems.
hope this helps Tim

You can't over oil the distributor oil cup.

Hi kwisor,

Humble opinion for any Model A driver's safety.

FWIW:

1. If your gas tank still has dirt in it, and/or flaking rust, and/or has peeling old gas tank sealer, and/or "anything" that can stop up the gas shut off valve, the fuel line, or anything in the carburetor including jets etc., be prepared for a very similar repeat occurrence that leads to a possible complete stop on a highway.

2. If tank crud is only "minor", the cylindrical screen protruding into the gas tank attached to the top of the shut off valve can help as well as also installing the "inside of sediment bowl" NAPA 3039 filter.

3. With or without passengers, please do not get caught stopping on a two lane highway with no shoulders in todays traffic with a fuel starved engine that could have been prevented.

4. Today's older & younger drivers have either no knowledge and/or have forgotten that vintage cars years ago with tubes had flats and/or were sometimes having minor break downs, thus being stopped & parked in the middle of a lane of traffic for minor repairs. We seldom see cars "stopped" today as compared to years ago.

5. It can even be less safe to be stopped & parked in hilly road lanes where one cannot see on the other side of the hill.

6. Just concerned for anybody's life safety, young or old because an 80 year old dirty Model A fuel tank with "new" ethanol gas can cause severe "new" problems never witnessed before with one's most fine tuned trusted Model A.

Hi Kevin,

It really happened to me a few months ago on a two lane highway with no shoulder, just around a blind corner with vision around this particular corner totally blocked by a large live oak tree on the right side highway shoulder. Eighteen wheelers were whizzing by at 55 mph, one after another.

The gas shut off valve got clogged so I pulled the choke rod out & was able to travel another 20 yards & then coast in neutral with a stopped engine to a driveway on the right on an abandoned lot.

Without any hesitation, I disconnected the steel gas line at the carb, loosened the connection at the sediment bowl, rotated gas line upwards, removed gas tank cover, & blew in gas line to blow crud back in tank -- took a chance & made it back home about 3 miles away; but stopped half way to repeat clearing the fuel line just in case of another blockage.

My son who was with me asked me where did I learn this remedy on how to get it running again as such -- told him about my 1930 Coupe I bought with my very last $25.00 (55) years ago -- did not have time to explain all the tricks we learned back then about how to get them going when one is young & totally broke.

Anyway, it appears that we can never have too much respect for the very kind people we encounter in this hobby; & it is most informative, (& maybe sometimes embarrassing), to take the time to relay our past "close call" life threatening experiences to help others.
