My issue was an exhaust leak between head and manifold when o took it apart I noticed two studs on the head where broken thats why it had a exhaust leak when i took it apart the intake from the exhaust manifold one stud was seized so instead of re thread the broken one I throw it away , bought a Dorman brand that was junk , and ended up buying this one but I didn’t noticed that where the choke sits it was open and i can hear the exhaust smell the gases , know with this bowl should fix my issue
