Hey guys new to the forum. I have a Craftsman gt18 with the 18hp Briggs on it. The fuel pump seems to be working, but it wont run. If you pull the fuel line going into the carb and put it in the choke hole on top, it will run. I've took it apart and put fresh gas soak for an hour or so, just to clean any gunk inside with no luck. Any suggestions? Also theres a flat spot on the carb where it looks like something might bolt to it, but i havent been able to find any pictures of a stock carb.
Any help would be appreciated. Thanks!
