I don't know what you're all on about

is it worth doing on a mildly tuned (system and filter, K3 cams possibly later) engine zadar?

not in my opinion.maybe with built motor and fancy fuel.
I used it on very built motor but for retard,not advance.

I always felt the advancer gave a nice low-end boost, but then I was less choosy back then and it could have been Modder's Disease... No idea now, I might take mine out and see if I can tell the difference.

Ref: I used it on very built motor but for retard,not advance.

That'll be why you never noticed a different ! Retarding the ignition will make it bang far too late when the piston is allready on it's downward stroke. You just detuned the engine.

Ah, you slot the pick up not the trigger. Now I'm with you. Which way do you go ? Clock wise I imagine if an anti clockwise adjustment on the trigger advances. Any body got any pics ?

not really,depends how motor is built.
my dyno testing I mentioned was done on stock motor.

yes,clockwise for advance.

Yeah, it sure is a black art. You must have been running a high compresion ratio ?
I used to have a problem with pinking on an A+ turbo engine I built. I was using 10.5:1 compression to negate some of the turbo lag from running a Garrett T3. Worked great untill I blew the piston to into a million bits. It would have been fine if I'd left it running 0.5 bar but I couldn't resist playing with the boost pressure. Damn cabit mounted bleed valves !!

actually less compression than stock,just a lot more hp

is this the little feller I need to slot? The strip metal bracket it's sitting on ?

Cheers guys.
