RJT>MR>What with engines getting smaller and running at higher rpm to make up
RJT>MR>the same hp's, a mechanical ignition system will eventually have the
RJT>MR>points floating at those ever higher rpm's. Points are less practical
RJT>MR>now with computerized engine control systems.

RJT>JE> Not less practical - totally impractical!

RJT>And yet they seem to use points on a lot of other stuff,  outdoor power
RJT>equipment and such,  for example,  which typically has lots smaller motors and
RJT>runs at higher than automotive RPMs for the most part.  Idle speed for a mower
RJT>is what,  1800 rpm?  That'd be a low highway speed for my car...

My riding mowers haven't had points for years - tis
electronic. Jay
