Stumble
My truck has a stumble at around 1000 RPM up to 2000 RPM. It does this while driving and in park. It takes off fine from a stop, but while driving slowly (5-10mph) it stumbles. It's fine at higher speeds, and just started this yesterday. Truck has 305 w/ 2bbl Rochester. Carb was rebuilt 1 month ago. I heard of similiar symptoms being caused by a bad module?? Any ideas?
Thanks in advance for your help!

Re: Stumble
Doesn't sound like a module to me. They either work or they don't. If nothing changed and this just started happening I would tend to think it's fuel related. Maybe a lean condition. I guess there 'could' be something goofy going on in your distributor but I doubt it.
Good luck, B |

Re: Stumble
I forgot to mention that before this I was messing with the mixture screws. I was trying to adjust them and noticed that when I ran them all the way in that the truck still ran
 Would this be a vacuum leak??
