I tend to agree with your assessment of the Weber application. Just wondered if anyone had used this carb. The comments I saw elsewhere on the web indicated the Weber was a good fit. The tallest adapter I found thus far was only 2 inches. Probably not enough to address the turbulence issues you mentioned.
Keep in mind that the carb setup on this 235 was "as is" when I bought the motor. I did not buy anything extra for this setup, or do any mods to the motor. I'm simply trying to get the best possible information, before I go out and spend any money on upgrading the fuel system.
Right now, I have the OE manifold up at the shop being cleaned and surfaced. When I get that back, I'll restore the intake to a single YF carb and see how that works out. That should make the carburation more reliable and less problematic. That setup should be fine, and I can drive the truck until I sort out any required upgrades. If it is not, I can then make a decision concerning a new carb and/or manifold.
Based on the input from Carbking, I checked my YF carbs again. Both are 1-788, and the upper section of both were manufactured with an electric choke. If the YF 788 was made as a manual choke only, then he's right about them being modified. That alone may be the reason for the problems with these carbs.
Many thanks to all for your help. I will update as the changes are made.
