Now with winter here its time to put the car away and start on a couple of fixes on the car.
First is to recurve the distributor.
Years ago I had welded up the slots to lower the mechanical advance amount but wasn't sure by how much.
You can see the welds here.
When I had the engine on the dyno, it was checked and there is 20* mechanical advance. But since my engine has the KB107 pistons in it and they are hypereutectic - I've read that total timing shouldn't exceed 34* when running this type of piston so I had to back off my initial to 13* which gave me a safe total timing of 33*
I want to tighten that up.
A buddy of mine had made this advance plate.
I think he copied the one that FBO offers (or offered at the time).
So I pulled the distributor apart to installed the limiter plate.
But first I wanted to compare my welded up plate with the 20* slot on the round plate to see how close in comparison are the slots.
Yup, pretty much right on the money.
This shot is comparing the 12* slot which is what I'll be using to the welded up one.
Quite the difference.
So with only 12* total mechanical advance I can have the initial set to 20* and the total will come in at 32*.
Time to reassemble.
I cleanup and repainted the vacuum advance pod - I gotta wait for the paint to dry to finish it up.
