C22 Vac Hose connections at Air Cleaner end



C22 Vac Hoses

Convoluted as it seems , but prior to removing the C22 carburettor cover, it is prudent to remember all the hose connections before doing so as the various components connected require the right vac to perform properly. For fuel emission control purposes, the EGR connection on the left is crucial which essentially recirculates the exhaust gas back to the base of the Carb to reduce oxides of nitrogen. The other vac hose connected to the Carb body (upper side) which goes half round the top of the cylinder head cover is connected to the distributor Vac advance mechanism. Make sure this line display vacuum when the engine is running as this enables ignition to advance as the engine gathers speed.
