Settings for pump timing question.

[verdigo]

Yeah. My decimal placement is off. Must have been thinking in inches as I typed. I figured the setting would be okay. Actually my base setting was around 87 which would have been okay by Alldata. As long as I have you here another question I have is about the cold start device. The wire on this thing that connects to the throttle lever is looking pretty bad. How hard to start will this engine be if I were to just leave it disabled (In the warmed up position)?

Good call. The warmed up position is the preferred default setting in the case of inop. cold start mechanism. Otherwise, the IP timing is running too advanced during general operation.

The usual failure mode is a failed waxstat capsule. If the cable is frayed (and even if it is not), you should safety wire the adjustable stop on the end of the cable so it doesn't disappear when the cable breaks. Unobtanium.

My experience with inop. cold start mechanism has been fine, in cars with all GPs functioning, decent compression, good battery, starter, and 5w-40 full synthetic motor oil, in temps down into the teens F. In low temps, the first minute may produce a lumpy idle and extra smoke.
