Mac's on the Mintor

[Alan Simmonds]

Bob
I had the same problem with the 170 carb but found that removing the
throttle stop screw allows the barrel to be pushed a little further
through the body to make alignment of the pin / hole a piece of cake. Be
careful not to damage the O ring on the jet and the two O rings on the
outer (magnetic) part when you push it back in.  Also, I found that you
need to push the outer part ALL the way in to get the O ring to seat
properly and then back it out a little before replacing the retaining
and throttle stop screws. If the throttle barrel goes tight in operation
then the O ring is not seated.

Mintor owners....if you have to use the Mac's header, the flange has to
be relieved to make it fit because of the crankcase fins on the rear.
HYPERLINK "http://www.aeroslave.com"www.aeroslave.com sells a "jug" that
addresses this problem, but with a carbide end-cutter bit and my Dremel,
it was pretty easy work to fix the Header....
 
The 1.70 has a MOST interesting mixture drum in the carb....anybody ELSE
been inside that little engineering marvel?  HOW did you align the drum
rotor pin with the mixture drum actuator hole?  Sure looks like it would
be one of those "never, ever, take this apart at the field" items....
