You keep changing the question every time the other one gets answered. Do you know you are doing that? Is it to keep an argument going?
A 6V starter rotates a whole lot faster on 12V, which rotates the motor faster and thus delivers more spark cycles. Motor fires more in the same time as a 12V starter. Motor fires more, quicker start. As far as one revolution goes, if a motor starts in one revolution, it would not matter what turns it. That's just one fire cycle.
I do not know what you mean by "12V solenoid switch". Foot switch? Ignition switch with spring loaded position or a starter with a solenoid on top.
Explaining the truth, the facts and interpreting the posts for you is not sucking up. I don't suck up to anybody. I do respect some people.
