On my 1.7l one of the distributors vacuum hoses is disconnected and a bolt chucked in the end, why would this be? My mechanic servicing it has just spotted this and said that it would be giving me zero advance, so wants to obviously reconnect as per standard.
Any ideas why this would have been done by the PO??
A lot of 914s had the vacuum advance hose disconnected from the factory. The distributor only used the vacuum retard port. It didn't even need the hose on the vacuum advance, but a lot of mechanics would see the fitting and assume that a hose was supposed to be there.
Both the vacuum advance (when needed) and the vacuum retard went to the throttle body. Do you have 2 fittings on the throttle body or just one?
