Hi Len, I have converted the single ZS on my 78 Spitfire to a dual HS2 from
a 67 SPitfire. It made a big difference for me in terms of performance
and gas milage. That is mainly due to the ZS's auto choke on my car not
working.
The biggest problem with the coversion was the jets. The rebuild kits
that I got had the wrong size jets, they had an inside diameter of .10"
instead of .09". This caused the car to run rich no matter how I
adjusted them. It also turned out the jets for the front and rear carbs
are not suppose to be the same, so a rebuit kit that does not specify
what kind of jet it comes with should be avoided. Instead you should
just buy the gasket kit and get the jets seperatly.
The proper jets for the HS2 conversion are:
AUD9104 (Front)
AUD9103 (Rear)
Also, the BO needles form the 69 Spit smaller engine should be changed.
The proper needles AN should be used for the larger 1500 engine.
You can have a look at my conversion with the home made throttle cable
plate at the following links:
