First..I should explain how I got where I am.
I have acquired a '72 40 about a year ago. Not long after I got it home I discovered a bad crack in the exhaust manifold near where one of the "ears" were for one of the mounting bolts. It had been "repaired" once before with what appeared to be Quicksteel.
My route was to replace the exhaust manifold. In cleaning things up I found the stamp on the block indicated the motor was from a '78. Great, I thought.
In researching and looking for replacement exhaust manifolds is when I figured out that whenever motor the swap was done, they utilized the exhaust & intake manifolds from the '72 as well as using the carb from the '72.
I was able to locate a set of manifolds from a '78 and got those, mounted them up with a fresh gasket etc..
In going back to mount the carb back I found that in the top of the '78 intake is a bolt that runs vertical holding the intake/exhaust together where the '72 manifold didn't have one.
When mounting the carb back the throttle cable guide binds on that bolt head not allowing the throttle mechanism to function.
I have the appropriate gaskets etc between the manifold & the carb. Question though.... is there a viable way to "raise" the carb a little so that the throttle assembly clears that bolt head? Or am I stuck looking for a carb for a '78 so that it will mount and the throttle mech clears the bolt head on the '78 manifold?
