Jacob,
i'd have to dispute that thought.
properly built that little mc 1-41 will make about 5 hp which is a pretty standard kart motor size.
and converting mcculloch saws over to kart motors is simple.
you just remove all the saw parts and add the correct manifold and stuffer.
some of the engines will require ports to be added and all can be hopped up using the tricks of the day.
biggest problem is usually the stepped crank and Scott kneisel can make an extension for a decent price.
with a 1-41 you'd have a mc5 motor spec which while not a big time racer certainly will run fine in the historic class.
as far as the saws from that era i use the correct saws from that era and built exact copy mc10 clones a desirable and pretty fast little motor.
sorry for the rant but it seems to me many vintage guys are opting for a mc9 series "big" motor on the older karts that never had them.
the typical excuse is there aren't any decent correct motors or they're to rare to risk so i got me a mc91 or mc101.
with a little thought and research these old saws are easy kart conversions.
they will give you a motor that would have been found on the older karts.
of course if you're just about being the winner you wouldn't want one.
a bunch of the east coast guys are having a blast building seriously slow karts.
they are all about the same in performance and nobody is building cheater motors.
at Avon there was a whole field of trash talking 25 mph karters that had a "BIG" race.
i seriously doubt anybody cared or knows who won that "race" but they all are still smiling about it.
