I took the 1937 Ford 85 HP out today for it's second engine break-in test drive and it looks like my first issue which was posted a week ago ended up being a bad condensor. Thanks for the help Guy's. I'm still going to send a coil to Skip for a rebuild though. I have three issues I'm hoping you can help me with.

1) I still cannot get a charge out of my generator. It has been rebuilt with new brushes and when I move the 3rd. brush around nothing makes a difference. The ammeter gauge reads zero at all engine speeds. I put an old original cut-out on the generator and it moved quickly to a discharge.

2) For the first 5 miles or so the engine ran smooth then slowly roughened up. Now with the engine at idle if you stomp on the gas pedal there's a big flat spot then rev's up. Inside the car you can almost here the engine RPM slightly go up and down. The engine seems to run best at one turn out. The 97 Stromberg was purchased from Charle in NY.

3) I'm not sure if my plugs are right for the car too. I'm using Champion UC16. The engine has been completely gone over and was bored .060 over. I have put only 20 miles on the car. At my first drive the plugs were nice and clean. Now they are black with a scary sign of wet oil deposits on them but not bad. I'm wondering if the heat range is wrong. What plugs to you Guy's recommend?

Thanks, Again! Don
 
I would say you pulled up some dirt out of the tank ,its got in the low running jets ,Pull a plug wire and see if its a nice blue spark ,Generator .Set up a spare amp meter or a Multi meter on the carb side of the cut out to a wire from the battery or the main hot wire there and see if you get a reading
 
I use D-21 champs fairly hot plug. Charlie does excelent work. Poor running could be low batt. voltage if its not charging. ken ct.
 
Did the generator test ok after the rebuild? There's more to a generator rebuild than replacing the brushes. If that's all that was done, there may still be other issues with it.

Low voltage can cause poor running engines. You should be able to bypass the cutout for testing purposes.
 
Don,
If you have even the slightest thought that the carb is not right
send it back pronto. I road test every carb prior to shipping but things
happen.
Feel free to contact me off site at cas5845@yahoo.com.

I notice some non Ford pumps do not have the filter screen so it seals correctly .i recommend to run a modern filter in the line before the carb if your tank is not new .
