170 brakes

The other day I put new brakes on the 170 and didn't drive it after I drove it today and when I mashed the clutch and it stopped after a few feet when I mashed the brake nothing happened so I looked through the shifter to the brakes they were smoking then I looked up and there was a little white smoke coming from the exhaust I looked at the carb it was poring gas out so I immediately whent back to our basement how can you adjust the brakes on this I don't see any adjustment like the craftsman brakes I used to working on
