the engine is a genuine low KM (about 120,000km) and comes with factory everything such as B210 distributor, twin hitachi carbs, factory twin carb manifold, twin outlet exhaust manifold, all accesories like 12V coil, water pump, fuel pump, alternator and errr just about anything thats bolted to the engine. So what would the desired set of webbers be? I see on Ebay there is a pair of 40mm Mikunni carbs and manifold for $700 I think it's a bit rich though? and A guy in newcastle is selling a pair of 40mm dellorto carbs too I am guessing these will fit the A12GX intake manifold with perhaps an adapter plate?
