Exhaust leak...

Choke pocket was the culprit for the leak. Is there a gasket that's supposed to be there? Because if there was it was ashes when I unscrewed it and lifted it off lol. I kinda cheated fixing it up..... I used the old exhaust gasket, cut out a hole bigger to fit the bowls underside, threw on some gasket sealer and wrenched the choke pocket back on. Poof leak gone.
