CARBURETTOR ENGINES

Check

PERFORMANCE ORDER

1. Disconnect hoses from a tank and the thermal vacuum distributive valve (TVR) and blow.
2. TVR will screw in the right part of the soaking-up collector. On the cold engine disconnect both hoses from TVR. Blow TVR, attaching an auxiliary hose to unions. Air has to pass through TVR only on the heated-up engine.
	3. The tank is mounted in a back left part of a motor compartment.
4. Disconnect a hose And from a tee. On the working engine create depression on a hose, – at the same time turns of the engine have to increase slightly, leak in a hose should not be. Attach a hose into place.
