<VV> Sputtering

[Joel McGregor]

You are going the wrong direction.  Sputtering is not from lack of fuel.  Lack of fuel causes a bog.
Depending on what you mean by sputtering it is either too much fuel or an ignition problem.  Most of the too much fuel problems are worst at idle unless it is a stopped up air filter so I would start with ignition.

Everything was fine with my 66 Monza for a while until yesterday when on a short trip to town it started sputtering when I floored it (power glide transmission) . When I backed off the g as pedal it ran and idled OK.  I removed the fuel pump and it seemed ok.  I blew air into the fuel line and it bubbled into the gas tank.  I'm ready to order a new fuel pump, but I was told that because it is a diaphragm pump, it's either good or not good...nothing in between.  Is that true? Maybe it's just carburetor s?
