[DML] Re: Sputter when cold.

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

Being a mechanical fuel injection system primeraly it cannot operate
like a modern system. It is "normal" for it to act that way. Some seem
worse than others. There are some things you can do to minimize the
sputter. Clean and gap the spark plugs as close to each other as you
can. Replace the ignition wires if they are old. Replace the ignition
coil if it is breaking down under load. Check the initial timing and
the mechanical and vacuum advance to be sure they are operating
correctly. Correct any vacuum leaks. Make sure the vacuum lines to the
CPR are routed correctly and do not leak. The cold start valve is only
operating during cranking when cold. Once the motor starts (or is
warm) the cold start valve is inactive. The CPR could be part of the
cause but it usually is a problem not so much immediatly after
starting but during the warm-up period. If the car runs well during
warm-up and when warm the CPR probably isn't the problem. The other
solution is to just drive a little easier on the throttle for the
first mile or 2 till it can warm up. Until the car warms up some
systems are not active and others are locked into a "warm-up" mode so
it will not run as well cold as it can warm. That is just the way it is.
