Hello Everyone,
Anyone here in the Minneapolis area, I've got a 1936 Plymouth with a rebuilt motor, I can't get it to run well and am perplexed. I should say that it actually runs beautifully for the first start of the day and until the engine warms up. Once it's warm, the engine won't rev past a certain point anymore and it will cut out and surge, if I bring it up to the RPMs where this starts happening and sustain for a little ways, then it will backfire. None of these symptoms occur when cold. I've messed with everything trying to figure it out, would like to know if there are any experts in my area.
Thank You!
Jonathan
