Well, here we go again.
The new problem that has me scratching my head is that my 1978 Dodge W-150 has an engine sputtering problem.

When the engine is cold, it sputters, but i have all of the drive power I need.

When the engine warms up, the sputtering goes away.

I replaced the air filter and that didn't help

Then I replaced the fuel filter. No luck there

I used HEET, no luck

I used Seafoam, no luck

I even sprayed Carb cleaner down the Carb breather tube. I'm out of ideas.

I was having problems with the butterfly. It's an electric choke, so should i replace it with another electric choke, or a manual one

Might as well stick with electric. If the coil is operating then replacement may not be necessary. Most electric chokes you can loosen and rotate to apply or release tension on the butterfly. If there is not enough adjustment you will need to replace the choke. Also make sure the linkages move freely. A liberal spray of carb cleaner should do the trick. What you are looking for is fully closed on a cold engine slowly opening as the engine warms up to finally fully open on a warm engine.

It's a 2 bbl Carb. All I can find are chokes for 4bbl carbs. Anyone have any sources for 2 bbl Carter carb chokes?
