Holley is dated to 94' and has not had much use,it was bought then stored in the loft.
It was rebuilt over xmas 07 with a genuine holley kit,powervalve was replaced at this time but i guess it could be to blame for the over rich mixture.
Im gonna order another and see if it helps...

Another thing, I install power valves with the spring towards the sky and the metering block above that so the gasket seats properly.Don't put the metering block on the moon though.

Ok,new Holley 6.5 powervalve fitted and still no difference,the old one was ok but i swapped them out just to be sure.
Its a shame none of you guys are local as it needs a fresh set of eyes over it to see if theres anything i have overlooked.... ;D

Hmm,  may be a cracked metering block. . . . .Or the vacuum to the power valve circuit is blocked, so the powervalve sees zero vacuum and stays in enrichment. . . . .? Sorry for being wrong on the powervalve :(.

No apology needed my friend as its eliminated the powervalve being the problem.Next thing to look at is the metering block then and work back from there to the rear bowl.
I'll put some air through it tomorrow morning and report back.
Thanks for your input so far TexasRed...and vile of course... ;D
