Ok what the gently caress.

Twitter OP posted:

so you're not supposed to be able to do this with 4A's!
people have been attempting but had issues with creating an interference engine that you can't time correctly, so we mismatched it with custom timing gears & a vacuum actuated timing advanced distributor!

A lot of cars had vacuum advance distributors before electronic ignition.

Yeah it�s super common, there was a vacuum solenoid that physically rotated the base of the distributor as vacuum increased.

Basic, but better than nothing.

Better than flywheel-actuated timing advance. And more reliable than having a lever on the control column to adjust the timing yourself manually for various regimes of engine operation.

That seems odd, because if there was a vacuum leak wouldn't it gently caress everything up?

It would have to be a pretty big leak that was interfering with other stuff as well.

There was also centrifugal advance, so you wouldn't notice it that much. Proper vacuum advance helps the car run better, but it's OK with less than optimum.

Vacuum advance is manifold vacuum based therefore load sensing.
Mechanical advance is engine rpm based sensing.
A combo of the two solves for most operating cases.

Vacuum advance diaphragms crack causing all sorts of driveability problems.
They've been around since the 30s with buick and went away with the advent of distributorless systems back in the 90s.

Not only do they crack, but unlike electronics where you know if you have a bad ground, vacuum problems are a huge pain in the rear end to track down and it's often easier to replace the whole system

are you imagining a system where it actually derives the signal for when to fire the spark based entirely on vacuum pulses (nobody does this), or have you really never touched a distributor with vacuum advance (pretty much any non-race distributor you'd see IRL)?

Sure I've touched lots of distributors and changed lots of caps/rotors, but I never knew that any of them had anything to do with vacuum tbh

My car has an electronic (hall-effect) ignition with a distributor that has both centrifugal and vacuum advance. The electronic part is just a transistor that fires the coil - no brains whatsoever. No points to worry about.

My car also has mechanical fuel injection - a metering plate lifts a valve to the fuel injectors, but mine also has an oxygen sensor that's controlled with an analog computer that runs a frequency valve to offset the resulting fuel pressure to make the oxygen sensor signal stay even. It will still run with the "computer" removed.

On my '66 Bonneville, there are four vacuum hoses:

power brake booster (big one)
choke pull-off (cracks the choke plate a bit when accelerating a cold engine)
Distributor advance
heat/defrost door actuator

The line once came loose from the climate control head. Took a few minutes to find out why my idle was a bit rough.

The Econoline has just the one, for the distributor advance.

A vacuum gauge is pretty much required when tuning an engine with more than one carburetor.

I honestly have no idea why you guys feel so old, my last car had a "vacuum controlled" distributor and that was a 93. I think Honda was still putting them into CRV's as late as 01, but I'm not as familiar with B series engines as I used to be
