Hi , All electrical new. Flow from Pump appears good , but i dont know what volume is required.

yep , carb just rebuilt and balanced. Thinking it may be electrical

Yep done all that , new coil, new plugs new leads, new fuel filter

Hi , I have recently bought a 1973 GTO 2000GS with 4G52 motor. Most work allready done, But goes great till 4000rpm then missies and gags. Fuel vent clear, fuel filter clear. Will rev thru when parked , but under load just appears to either run out of fuel or spark? Can anybody help cheers
