Re: HS4 on a Stromberg manifold

Hi Carter, all of the HS4 SU's are "handed", and will have the bolt holes at 
10 and 4 on one side, and the other side will be 2 and 8. Now the carbs you 
have may be older than the HS series, and could possibly be H4 SU's. I know 
on MGA's the carbs had the bolt holes at 12 and 6, but I believe all of the 
MGB's had them as described above. The HS4's used on Triumph and MGB's are 
identical, and will only differ in the size of the jet needle used.
