I got a free mower with a 5.5hp Briggs L head engine. I carburetor was a mess. I glass beaded it and put it in the ultra-sonic cleaner for hour and a half using full strength Simple Green cleaning fluid. I blew out all the passages I could and ran wire through them. I did not remove the welch plug on the side. Wasn't sure I had one to put back in. I checked to make sure the choke was working. Mower won't start without "liquid help" Found another identical carb in parts bin. Put it on and it starts on the second pull. I'm guessing I still have a passage blocked somewhere.
