[dd74]

On startup from cold, my engine runs fairly rough until it warms up. Would this be a fuel regulator problem? This is in a 3.0 with a hand choke (engine was transplanted into my '74).

Also..

After reading a piece on C.I.S. in a San Diego PCA article, it talks about the system's intolerance for dirt and moisture. I run 91 octane fuel and also plan to change the fuel filter. But is there anything else I can do (additives and such, possibly) that would clean out any dirt and/or moisture inside the system?

Thanks for all your help.
