thanks much for the help guys.
wrenchbender, reading the link atomarc sent, it appears the advance is to save fuel only and possibly not needed at all? am i understanding this correctly?
i thought the advance was to stop off-idle hesitation.
atomarc/wrenchbender, what about it being hard to get the carb to idle with non-ported vacuum; sounds troublesome.
help...
