[T3] FI Dizzy for Carbs

[Max Welton]

That's just a binary test Jim, one he has already done.

The parts aren't new and the combination isn't stock. So we're going to take some actual measurements and go from there.

We're going to find out how many inches of vacuum Adams carbs generate on his engine at this altitude under partial throttle openings. Then we will work out how many degrees of advance this particular distributor turns that signal into (degrees per inch of vacuum). We will also measure the centrifugal advance range of this particular distributor.

It's kind of like when you rebuild a speedometer. When you have the unit right there on the bench, you can test it to see if it is accurate. You wouldn't just assume it is accurate because the needle moves, right?

 You don't need a vacuum pump to check them. Just suck on it
 with your 
 mouth. It will either leak or it's good. If it holds vacuum
 but the 
 mechanism doesn't move, then something inside the dist is
 stuck.
