Thanks

I ended up using a 4150 metering block gasket & punched a hole in it for the IAB , the 4150 gasket blocks the intermediate circuit off , changed the accelerator pumps out to smaller ones also , this motor runs clean & screams through the rpm range , don't think i'll bother messing with the intermediate cicuit , will leave it blanked off.

Those tailpipes smell good , no overfueling & i can pull a chair up , obviously spark lead played a roll also ,will check for any lean issues when i get to the track.
