Hi Duncan
You are right to be disappointed.
With the set up you have and a light body as you have.
I would expect a good 65 MPH.
With your four speed gearbox which is direct in fourth and a girling axle (5.25) it should be super.
I am of course guessing but I would suspect the carburettor may be the problem.
It may be worth sticking a standard carb on temporally just to compare if you have one, if you haven't I can lend you one.
Then you can plan your next move.
My RP which is heavy of course will do 55 MPH and he is all standard apart from the rear axle which is the same as yours.
