SOLEX 36IV CARBURETTOR USUALLY FOUND ON MILITARY SERIES - ESSENTIALLY A ZENITH 36IV. IF ANY ISSUES ARISE IT IS USUALLY DIRT INGRESS FROM WHEN YOU PULL YOUR OLD FUEL HOSE OFF AND REFIT IT TO THE NEW CARB - I STRONGLY ADVISE YOU FIT NEW E10 COMPLIANT HOSE AND AN INLINE FILTER JUST INCASE YOU HAVE AN OLD RUSTY FURL TANK.
