Good point about the little hp twins, Sandy. But this guy (see link) was ahead of his time preaching clean air in no. CA keeping Lake Shasta n Lake Tahoe perty and free of 2 smoke emoluments, err, emissions. A fella can still wake up and smell the pine up there, or maybe the medicinal skunkweed, anyway
Love to send this guy a picture of a Moesly with twin or triple Homelite Bearcats on it. Pretty heavy motors for 55hp.
