there is nothing more complex, ! Called engine tuning....
engine CR, that be first if not at spec. all is wrong ! 2x both the CR and the quench, areas... PING city, unless high octane fuel is run.
on cars with custom carb's like this car ,the carb and the spark are tuned together on a dyno ( takes weeks of work, lacking this dyno mach.)
in a factory car, the carb is already tuned and all you need to do is get the spark right matching that stock state of fuel flow. (called spec)
in this case it's the 2 fighting each other.
case in point, the advance is based on , fuel air ratios. if rich? the flame font is slow, if lean the front is faster. so spark is timed to MATCH THE CARB.
not the other way. (or pull out hair)
lean burn loves to ping, so, we avoid that.
btw, Suzuki dont make distributors, they do spec them and MiTsubishi makes them or Denso to their spec. (gear fit and advance spec)
when you are parked, and in gear, and slam down the throttle what happens?
the CARB goes super rich, this is a special feature of the carb, all carbs do that.. and can be very crude.
but it will go from 14.7: 1 AFR to 12:1, rich (best example)
this very rich fuel mix, allows a burst of more power, 12:1 is max power, 14.7 is min fuel , min smog. see?
so many race engine run 12;1 all the time, (not indy,500 or where fuel waste is an issue)?
but max power is great for driving from say 0mp to 20mph, (any time you accelerate the fuel goes rich, so needs advance NOW not 3000 rpm later)
this rich fuel burns slower, a slow flame front it's called.
and needs longer time to burn that fuel, it's so slow, and if not its just blown out the exhaust tips.
this is what vacuum advance does, its advances spark at that burst of vacuum at the calibrated carb port, (my guess, long long missing, now)
Centrifugal advance is easy, see? it just RPM, but vacuum advance is the most complex topic there is.
that is because it has many parts that must work together, as ONE. (and are spread out) case in point, I bet your vacuum is dead wrong....
it's not just a part thrown on a car, sure if stock an sure if 1 stock part added, but yours is anything but stock.
one could just not run Vacuum advance at all and just use lower gears.
but with a A/T you have no control its calibrated for a stock car, that you dont have.
in 5speed STICK, 1st gear take off will be weak but...
but once moving you can run 1st gear longer, and shift later, SO you get the benefit of the Centrifugal advance, say up a hill.
I'd hate to see you import expensive parts only to learn that your ported vacuum is dead wrong for any suzuki distributor.
can be.
its ported vacuum and that too, is complex. the diameter of said port and exact location are critical to the feature.
I have no secret suzuki list for what real mitsubish partnumbers were used, sadly
