I would agree that it depends on wear in parts, the correct ignition parts, carbs, head work, fuel rating. It's not unknown to get an engine with a mix and match of lotus and jensen spec 907 parts. I had my JH set up on a rolling road and the advance that gave the best power was not as per the factory, from my addled memory it was 14 degrees. So I would recommend this route (albeit more expensive) if you want to get the most power out on an engine. May also tell you other things about the state of your engine - is that always good thing?? One thing I found out was that was running a non ballasted coil on a system that had been converted to a ballasted coil - plenty of hard to find misfires and poor performance cured. I should have realised when the coil got so hot you couldn't touch it - doh!!
