Here's the deal:
discovered the other day that the vacuum advance on my dizzy is KAPUT! Before I had a chance to consider pulling it to buy a replacement, had my tachometer nicked from my car a couple of nights ago, another expense! Add to that, some outstanding repairs that are required elsewhere on the car are likely to be a little steep. To top this off, January has so far been an expensive month and there's stuff-all of my pay left for other living expenses (I hate monthly pay
) Therefore it may be some time before I can get a replacement vac advance unit. What I want to know is:
Can I artificially advance the timing to compensate a little for the lack of vacuum advance?? The other day I blocked off the vacuum line to the vac advance unit and advanced the standard timing of 6° BTDC to 10° BTDC at an idle of 600rpm. Is that far as I can go? Could I go further?? The car isn't usually driven that hard, its my daily driver to work and back, and will occationally get a run on the Hwy to clear the cobwebs out. The motor is a 1971, 250 cu inch in an XY falcon (if that helps)
Any advice is appreciated.
Regards,
Teddy
