Re: [AMC-list] Engine Sputter

[Matt Haas <mhaas@xxxxxxx>]

Mike,

My first thought would be a problem with the accelerator pump in the 
carb. With the engine off, hold the choke open, look down the carb 
throat, and open the throttle quickly. You should see a steady stream or 
two of fuel shoot out of the side near the float bowl. If you don't see 
this (or it dribbles out), the accelerator pump is bad and you'll need 
to rebuild the carb to fix it.

Other things that can cause this are a vacuum leak, problems with the 
ignition system (mechanical or vacuum advance issues, improper point 
adjustment, bad coil), and/or general tune-up issues. Also, since the 
coil was replaced, you need to make sure it is for a 6 volt system and 
not a 12 volt system.

> Now that my '51 Rambler has brakes, I've discovered a problem with the way it runs and accelerates. It starts well with the manual choke and idles smoothly. When accelerating it bucks and sputters like a wild bull. The previous owner installed a new fuel pump, points, plugs, condenser, cap, wires all to no avail. FYI, still 6V system. Soon it will go to the body shop and get paint, but I'd like to drive it there easily.
