Advance / retard timing

[RedVK]

Hey... I am a relative newcomer to the world of holden, owning an average 85 VK SL. My 202 Black seems to be detonating....... how do I manage the timing so it's actually running properly. Right now, the rev range is extremely 'slack' as in about a 40% loss in power over other stock VK's I have driven.

Idle @ 950
High Idle @ 1150

fuel mixture is up the date - averaging 22L / 100km.
Engine runs on after ignition cutoff.

Replaced leads with 8.0mm Monster leads
Standard NGK's gapped correctly
Standard air filter element

I didnt realise this was the case with the 202 Black, but there are several issues relating to the E.S.T. also.

I am not a highly technical person, but if someone can lay out the steps, i can perform it with no worries.

Cheers

The idles a bit off off but not to far.

Do u have headers on this ride at all?

850-900 idle

1100 high idle

Those would be something id be aiming for, but u have a black mortor with EST so i don't know.
