Jerry,
(Note: what follows is IMHO) The reason that the different damper oils
you've tried failed to have any effect on throttle response is that the
damper action doesn't have anything to do with throttle response! The
oil in there is to provide a resistance to the damper (and the
accompanying needle) rising, thereby creating a momentarily richer
mixture. Voila - an accelerator pump! The air flow - throttle response
- is modulated by the opening of the throttle discs. If what you are
getting is "stumbling" upon application of throttle when the car's cold,
you probably need to use a bit more choke, or you're using TOO LIGHT
WEIGHT a lubricant in the dampers. (Or the oil level in there is too
low.)
I just realized this is a rather curt message - not intended to be that
way! Would be glad to discuss further.
