It develops so much more power, honestly mate it is worlds apart from dizzy + 14cux
Mainly because the timing is accurate, then because the spark is fat (I have increased the plug gap by 0.2mm also!) and also because I can now run target AFR and tune the engine with performance in mind.
It is easier said than done writing your own fuel maps believe me, but you can squeeze more economy out of the motor too if you are careful with your igntion advance.
Me personally will be happy to cruise at 14.5-15:1 AFR which is lean enough for cruise and plenty safe/cool, but I can now run a guaranteed 12.5-12.8:1 WOT mixture and super lean on overrun, which saves lots of fuel. Popping and banging on 14cux was awesome going downhill but it was literally pouring petrol into the exhaust, not ideal.
It really is a different story on MS, no more jerky hesitant running, just smooth dependable power.
Will do an underwater video one day, planning to submerge the engine and fire it up but need to sort out a breather pipe for the power steering reservoir first!
Sounds like you've got yourself a good setup, look forward to seeing videos!
