Thanks Terry,
Snuck off to the shop today after a big Easter lunch to confront the throttle linkage. Was worried about it fitting after reading about having to modify the linkage when installing a later model motor. Made a couple of 1/2" spacers to go behind the linkage at the water neck, and to my surprise it fit the 235 with no problems! Made up a couple of new rods, and I was home before anyone knew I was gone.
Thanks, David
