That's an early dizzy you have, 5k's didn't have a screw on the vac advance.

 

But 3k's did.

thats what i thought, so its not a electonic 5k dissy

ok lads i took a shitty camera phone picture considering it is night time outside hahahaha,

 

No this 5k doesn't have a elctric dizzy i think somewhere along the line i got ripped off >| :P

 

But there is a little knob looking thing poking out of the side of the dizzy and you adjust the vac advance with that, i will try get onto the computer so i can modify the picture abit better

 

But here is the picture

Yeah that's an early 3k dizzy, they're the ones that are easy to lock up for boosted applications. :yes:

 

I don't think the screw really adjusts that much, maybe 2* at most, so don't stress too much about it. From memory the vac advance is supposed to give you around 8* so you can check that with a timing light pulling the vac line on and off.

yeah it's just becoming a pain in the ass when tryin to start it as the car starts then wont idle :hmm: (don't just think oh it's ya fuel mixture, adjust that :/ i have and now i'm onto timing) cause the motor ran fine in the 36, now it's in the 70 it doesn't wanna do it.

 

I just wanna know how many turns from it being screwed right in is it supposed to be out?

Hi, there should be 3 red lines on that screw. Set it so that the middle one is flush with the dizzy body.
