Hi to Manch and Jamskin,
Manch, it is up to you to decide which way to go, originality versus functionality....I went the Honda way and have never looked back, a beautiful little Japanese engine that just purrs....you may go for originality, and that is fine....but, Scotty 45's with a Briggs....there are heaps out there, so not that rare....the decision is yours, mate.

To Jamskin,

on getting yourself a fine engine...you are in for hours of mowing pleasure if you keep it well maintained...just remember, oil is cheap....engines expensive...oil change it regularly.
