Low vacuum on carb
Low vacuum on carb
Hi. I can’t get my rover 3.5 v8 to idle.Theres loads of vacuum on the near side carb but very little on the offside carb.It has zenith carbs fitted.could it be an air leak that causing low vacuum and are there any common places that it would leak from?i tried a search but couldn’t find an answer. Thanks Matt

Is the piston sticking?
Or (although rare) has the diaphragm split?

Thanks. They’re ok. Going to get it smoke tested.
Re: Low vacuum on carb
If there are later carbs fitted, there should be an additional spring loaded valve fitted in the throttle valve. When the spring got weak over the years there is an bypass at idle revs. The best solution is an exchange to the standard unit without valve or the valve can be soldered.
