OK, I have read a lot of post on putting a turbo on a 12a. Most of which say to lock the ditributer. Now I just wanted to know how to do it. What exactly do I have to do to lock it?

 

You can pull the dizzy apart EASILY. Take the vacuum advances off, take the screws off and pull the guts off carefully, and you are left with the weights and springs. You can remove the springs and tac a wield on each of the weights so they are out and you have max advance all the time. Make sure you put the vacuum diaphrams back on so they have the correct L-T split though.

 

you have pictures? that would help me alot.

 

If you open up the dizzy you'll see. It is very easy to do, and is exactly how WackyRotary described it.

 

When i put the vacuum diaphrams on i dont hook them up to the vacuum signal correct

 

Correct. Also, make sure to rotate the outer shaft for full advance and then tack the weights. This is so if the welds break, it won't accidentally advance itself and kill your apex seals.

 

Good point!

explain this to me in dummy terms. rotate it clockwise or conter clockwise

 

Rotate it in whatever direction moves the weights outward. I just did mine and I don't even remember

 

I'm not exactly sure what outer shaft are you guys talking about? All i did is wire the weights together. Was that a bad idea? What would be some of the signs if the wire came loose?

Oh yeah, there is an easier way to get to the weights through the bottom gear.

 

if the wire came loose, the weights would be thrown outwards if you were under load, (gas pedal to the floor), and it would advance your timing to a dangerous level, and could make your engine blow an apex seal out an exhaust port or two...

 

Well, I think I screwwed up please check the pics. the parts in circled in red, should go into each other right.

yahoo photo album

 

is there any benifits to locking the dizzy with just a stock motor ? or is that a bad idea ?

 

It's been a while since I opend up a dizzy and the pic's kind of blured but yeah I think you screwed up.

 

Ah, that's a 12A dizzy.

 

well time to pull out the dremel and grind those little bad boys off.
