Hi All
Does anyone have any advice on which Amal carb to fit to my engine.
The engine is a 1960 650 A10 but with an A7 head re profiled to match the larger 650 bore.
The engine has standard A7 valves, 356 cam and flat top pistons.
Head inlet port measures 1.060
I have a 389/45 1-1/8 and 389/15 1-5/32 carbs available to me and need to decide either to use one of those with the correct jetting what ever that may be or look for something else
