Yeah, exactally, it idled great, was perfect in low gear, but in high gear, was a complete slug. My dad had just said, that (when I switched the Tillotson I measured it), I should put the same size Mikuni on as the Tillitson, so a 34 Mikuni and a 42 Tillitson wern't very close, so I bought the 40mm Mikuni which is really close...
And I had to take the elbow off, you can't mount a Mikuni vertically, it has to be horizontal, using a rubber flange (that is bolted to the intake port) that the carb just fits into, and the rubber is tigtened around the carb with a hose clamp. See the photos, what I am getting at with all this, is that the carb is right close to the engine and might not clear the tranny. (I am sure you knew all this anyway! )
And it says on the side of the engine G44B... no SS so I'm not sure there...???
