I'm running a single HS2 on my 67 sprite w/ a metro manifold and I modified the
carb per Vizard instructions.
A couple of things to pay attention to.
1. The float bowl angle is wrong w/ the Mtero manifold. I had to file off the
"ear" on the float bowl so I could change the angle and get it level
2. Make sure the fuel filters and carb passages are clean. You're flowing all
the fuel thru 1 carb now instead of 2
3. I had to change dashpot oil to keep it from leaning out to much and dying
when I came off the throttle. Once I got the viscosity right, it was much
happier
If you have access to a rolling road dyno, book the time and fine tune your
needle as described in the carb mods section of Vizard
If you haven't added a ram pipe, do it. You're gonna LOVE the difference
(Embedded image moved to file: pic10988.pcx)
These numbers were circulated a while back and are the length (inches) from the
combustion chamber to the end of the ram pipe
I have mine tuned for maximum ram @ just under 4000 rpm
When you nail the throttle it really goes
I'll never go back to dual SU's
