HS2's should run just fine. In actuality...probably better
for normal daily driving than 4's on a stock mufflered Spridget.
The HS4's would give you better top end and grunt when
standing on it, but only in the upper rev ranges.
Also the smaller throats of the 2's will raise the velocity
of the air in the intake, and have a wider working range
of piston vs. air volume.
Now if you free flow the exhaust, a header and maybe a cam....
yes...go for the 4's. Until then.... I'd say save your money...unless
you simply like to play. :-)

Subject: Special Carb setup
Hello listers
My car is a 75 Midget
I've owned it for a little over three years now
And have yet to come by someone with the same carb
Installation.
I have the 1500 engine with dual SU except my carbs are
1 1/4" SU HS2 AUD275 from a 67/68 Spitfire (1296 engine)
Needles have been changed and a lot of tuning done...
they sometimes overflow when hot and vaporlock due to improper
Heatshield protecting the floats from the header. Since its a mod job I need
to replace the heatshield that was made when this installation was done its
not large enough and heat still makes its way to the floats
Now I baught the car like that, I've done a lot on the car
Since I've baught it and am now coming to that crossroads..
The carbs.
1) Has any of you here seen or driven a car with a similar setup as mine
If so does the fact that I have HS2 carbs where I should have HS4 mean that
the car is lacking power? I have yet to try a car with dual HS4.
2) I'm questionning wether I should buy a new set of HS4 carbs as they are
kind of expensive...and I cant seem to find any used AUD665s
Thanks for your comments
