Maybe a silly question

[cootertwo]

I was wondering, how many revolutions of the crankshaft does it take, to fire all 3 cylinders? Also does the crank position sensor send only one signal, per one revolution of the crankshaft?

Two revolutions are needed to fire all three cylinders. Then you are back at the front of the firing order ready to do it again. I don't know the answer to your second question.

Later,

Wasted spark !!!

Warp, was just wondering if a simple electronic ignition module could be made to work off the crank position sensor, and then use 3 carburetors. Never seen it done on a Rocket, yet. The benefit being simplicity.

While installing the carbs convert the engine to two stroke then it will only take one turn to fire

Make it a diesel then it won't need a spark at all.

And go for one of those Triple choke down draft Webers
Now that would look cool.

Finding some one to tune it would be tricky.
These are amazing Carbs, very complex, but with some one who knows what they are doing they can be made to run awesomely.

Had a little experience with a two barrel Weber on my Pop's hopped up Austin Healy Sprite. Nice that you can not only change all the jets, but the venturi too!
