60 sec divided by 5,000 gives 12 something.  wonder if we need to divide
by2.

If going by O2 for mixture please don't.  The a lot of acrhive stuff about
how poor of job it does.   Do a couple plug cuts and get back to me <g>....

If ya got the need to tinker (assuming ya got a G-Tech, or something to
accurately measure improvements) the try taking a couple % off the high
gm/sec area.
If ya get any knock retard back up
