just saw this i really haven't been trolling all the pages as i should.
first who ever said building a mc10 clone is cheap i never did.
i set out to build clones because i simply couldn't find enough mc10's to suit my taste.
so i figured out exactly which saw parts would fit.
it took a while because the guys who did know what parts to use weren't really generous with information.
so firstly, making a mc10 clone is not cheap.
it will cost around the same as a "real" mc10 by the time you're finished .
the difference is saws typically have gotten butchered or totally used up.
they tend to have clean bores and the porting is nearly always stock.
the reason you use at least two saws.
mc10 clones aren't a true clone if you start omitting important parts.
the d44 provides the correct center plug head ,tin shroud , coil and outer cover.
very few mc 1-70's came with a center plug head and no 1-80's i've ever seen had them.
the s44a and s55a all have side plug heads.
you want to add a thin ring piston if you want to go fast and the other kart parts need to be added.
as with any recreation or restoration you may need to buy several parts donors to get decent clean parts.
recreating the mc49 is much easier typically you switch the crank and piston and you're done if all the ports are drilled.
easier yet is building a mc49 saw/kart motor.
with those you use a clutch suited for a stub crank and switch the piston.
of course the intake manifold, stuffer and motor mount need to be added. often the saw exhaust is fine for a mc49.
anyway my point is that we build the clones not so much for saving money as to add more kart engine inventory to the world in general.
they ain't making mcculloch kart motors anymore so we do what we gotta do.
hope this helps
