McCulloch Con Rods ...... for the 91, 92, 93 And 101 Kart Engines.
This con-rod made by Big Joe.
The one shown is for the Mc 91 / 92 / 93
I believe that the rod shown to the left has a larger gudgeon bore as it carries the needles therefore the claim that this rod and upper bearing set won't needle your cylinder.

These rods were made to suit the Mc93 and 101D
A very hard to find Conrod
