[Healeys] rebuilt HD8s

[Oudesluys]

When you apply the breaks you will get a difference in vacuum for a 
moment. This will change your mixture and idle speed. If the change in 
idling continues there might be a leak in the servo. Is it right that 
the AH has a piston type servo? If so the small leakage past the piston 
might be the cause.
Before the carbs were overhauled this may not have been noticed as the 
leakage past the butterfly spindles was probably to big compared to the 
small leak past the servo piston.
