After 1.5 years of building up the engine, together with the double 40DCOE Weber, tonight it was it's first firing up. Literally 'fire up', because I didn't attached the rest of the exhaust to the exhaust manifold ;). Together with not jetting the carburettors (see the backfires), it was quite a spectacle. Not something you need to do very often to get your neighbours angry :P.
