Hello Grumpy
Thanks, as always, for that succinct re-explanation. I'm sure it
never hurts to reinforce the basic physics of single cyl IC engines.
You will appreciate, then, my argument that 'apples should be compared with apples'
The old Briggs side valve alloy designs, dating back to the 1950s, should not be
used, or applied to, the modern generation of Honda and Briggs engines.
Your last paragraph - in particular - is a salutary reminder to all, and its principle
is clearly applicable to other long-standing 'which is better?' debates. It's best
to avoid general statements; better to compare model for model - apple with apple.
Cheers and thanks.
