Hello,
I have just taken delivery of a Hornet 60. I shall fettle it over winter for some vintage speed. The rear intake has a screw in jet one side and the other has the remains of a needle valve, about 1/2inch of thread and about 1/8inch of taper. Being lazy, anyone know the thread size on the needle and I assume the taper is probably about 3/8 to 1/2inch long, before it became vandalised?
Now to show my complete ignorance. The rather nice brass venturi is screwed into the back plate, however below the nice flare. there is an oblong brass piece that has the jet one side and the NV the other. Here is the rub, you cannot unscrew the venturi, because this oblong chunk of brass hits the centre casting extension which holds the disc shaft. Ok, I cannot see any joint on the brass venturi, i.e. the oblong was fitted (shrunk, silver soldered etc). It all looks machined from the solid. So how did the venturi get screwed into the back plate?
I am quite happy if you want to make a fool of me, there must be a simple answer!
Andrew.
