When the fuel bowl shows crud, there's plenty more in the tiny orifices of the carb - even a new one. You'll see my story on this problem in the January issue of The Rovers North News. My fuel bowl looked like a parfait jar. Every so often I still get a stalling after filling the tank, so I know there's more stuff in there.

Do check that your intake manifold nuts, particularly the hard to find one under the manifold, are tight. If you're sucking in too much air, you'l lean out the mixture so much the car will run very poorly under load.

Also, make certain the points are gapped correctly and are clean on both sides. With the engine running, take a spray bottle of water and spritz the spark plug wires and the coil to distributor wire. If anything starts to run poorly, there's another culprit. Replace the set.

Good luck,

Jeff
