Hello Scottm355
This is a difficult issue.
It all depends on the starting point of the owner.
The old 45 daily driver owners seem to have adopted the
replacement engine approach.
A smaller category of old 45 user want originality for various reasons:
historical authenticity or for personal nostalgic reasons.
My reality is that the Kirby was a great small engine, but I would like
to see other replacement parts made available - like those square mufflers!
A whole range of parts need to be available before folks
consider repairing Kirbys ... rather than replacing them.
I don't hold much hope - except for the purists.
I would love to be proved wrong.
Cheers
