Well, George!
I have a Mk1 Spit with a Modified 1500 engine that does just fine with a pair
of 1-1/4 carbs from a Mk3 Spit. In fact it goes like stink!
And Kas Kastner will tell you that he was able to generate 123 hp from a 1300
engine using twin 1-1/4 SU's. That was more than the factory works
department was able to get from the same engine using dual Weber DCOE's.
