Ook... Only 0.333. It was closer to 0.6 before the "must be running" rule ditched the 2002, the Ranchero, and the string trimmer...
How 'bout cylinder-count bingo?
1-cyl mower, 2-cyl motorcycle, 3-cyl car, 4-cyl car (idle), no fives, no sixes, no biplanes, 8-cyl van...
In reply to Ransom:
Ok 1cyl mower, 3cyl motorcycle and 4cyl car.
That Stat is the only one I'm likely to fare well in. Of my 18 complete cars, four are under 1.3 liters of displacement(classic Minis), one of the three v8s I have makes less power than any of the turbo four cylinder motors I have (1981 Rover SD1, Federal version. 118 hp out of 3.5 liters vs SAAB turbos from 175 to 235 hp. ), and the average car value of my fleet is somewhere between $1 and $2K.
0.286 if I have to only count running. (6/21)
1.04 if I don't ((6+6+8+1+1)/21)
The 2 1s are an ATV and a lawn mower, not running etc
0.047 on turbos (1/21)
That's one of the not running of course.
