I have a 64 Stude. 289 2 barrel carb. Stromberg 132.I have rebuilt this carb. and adj . The problem I have is at 15-20 mph. it wants surge. I can step on the pedal and it takes off like jet. and runs good. Any idea of what is causing this low speed surge?

May not be carb. Does engine surge in neutral at the same RPMs it would turn at 20 mph? The WW carb is a good carburetor; the Autolite distributor not so much. Check the timing and check both the vacuum and mechanical advance. Throttle shaft OK? Had trouble with my WW on my 64. sent it to a national rebuilder and it was over choked and it leaked. Hope it is now finally fixed. I can remove it or reinstall it in about 2 minutes now! The pcv valve is hidden away in the back of the motor - is it ok? Good luck! -
I did have a nos carb on the car and it worked great. I wanted to use it on my Daytona Convert up north. That is why I rebuilt this one. Timing is fine, pcv works fine.Comment

Is choke adjusted correctly? They can be very fussy. It is possible that if set too rich it could cause surging. Again, Good Luck. Surging can be frustrating. My Ford F One-Thirsty has done it off and on since new. I just speed up or slow down and attribute it to its being a Ford.Comment

Check the diaphragm on your vacuum advance sometimes when the are perforated they will cause a surge at lower steady speeds.Comment

The main jets may be too lean or partially blocked. Acceleration opens the bypass jet making the mixture a little richer.American iron, real old school
With two tone paint, it sure is cool
Its got 8 cylinders and uses them all
With an overdrive that just won't stall
With a 4 barrel carb and dual exhausts
With 4.23 gears it can really get lost
Its got safety belts and I ain't scared
The brakes are good and the tires are fair.
Tried to sell her, but got no taker
I"ll just keep driving my StudebakerComment

May be too much fuel pressure? Can cause surging. Electric fuel pump?? Check!!Originally posted by Daytona View PostdonComment
