Running Lean???

Just checked my spare manifold in the garage and it does not have the plug either.

My 48 does not have one there, but does have a connection for vacuum wipers. So both vehicles have a good source to check vacuum. I have a couple of other manifolds, but they are in the shed and I have not looked at them recently. Has been raining for days. appparently some manifolds had the plug, some did not.

Just to finish this old thread off, I rebuilt my Stromberg Carb. over the winter and got the car running again yesterday. Surprise, surprise, once the engine is hot, I can now idle the engine down to as low as 400 r.p.m. with no problem. I have set it to about 450-500 r.p.m. and it idles great. Took it out for a drive and it is now so quiet at stops that I can't tell whether it is running or not without looking at the oil gauge. These engines really sound good when idling that low. Now for the summer driving season - can't wait.

Congrats Phil;

Like a happy ending to a fairy tale hope you and your car live happily ever after.

Good deal Phil. As I was re-reading this thread I kept thinking your problem was a plugged idle jet circuit. This would make it die at idle speeds because it wouldn't get any fuel through idle circuit. Apparently you fixed that when you cleaned / rebuilt your carb.

Just had a look at my intake manifold and it does not have the little plug shown in your photo. The plot continues. Where did my intake manifold come from? Who knows!

Mine doesn't have one there either (1940 Dodge), but there is one just below the carb. Used for running the gas heater. In this pic it is just to the right of the part labeled "1". Yours may be the original 1940 manifold.
