@solo

How envious I am about your start !!! 😅

One sure thing is that when I plug a SuperB battery as supply (with Anderson park connector), the engine revs 50rpm more and the engine fires instantly

I do have a LiFePO4 battery, for sure it could help with the startup.

UPDATE 😄

With 24-2 toothed crank wheel, no more cranking issue. Engine starts instantly, cranking count is good.

With a little Lithium battery so with less cranking rev than SuperB.
