Hey guys! So, I got my Bolens walk behinds and well, I got one of them to run! But, it leaks gas and oil, but I was running alright until we put a belt on it and tried to make it move. It tugged along pretty well, but it kept stalling every few seconds it would run. So, me and my dad pulled the carb apart and cleaned it and adjusted it correctly. But, it still won't stay running, unless you take the air cleaner off and put your hand over the carb with the choke on. But, even then it only runs for like a minute. Any ideas whats wrong? Any help would be appreciated! Thanks! Ian.
