Sounds like the Choke is not working.

Check the linkage and tiny springs if this model has an auto choke. Otherwise, the choke cable may simply need adjusting. Remove the air filter and see what's going on. You should be able to see the choke with the air filter removed.

  • Replace the spark plug with a new one.
  • Start using a fuel conditioner and carb cleaner, such as StarTron , on the outside chance that a dirty fuel system is causing this issue.

Put up a video of it on your cell phone. TURN THE PHONE sideways while shooting. Need to see direction of fuel travel.

Good luck on you fix. The good news is that B&S 46 series engine was originally called a 20 hp. Later it went to 22 hp. Yours with a 16.5 hp sticker probably means it is among the last ones made.

B&S discontinued flahead, "L" Head, engines due to government regulations. They used up the last of their inventory by slapping whatever hp sticker on them the purchasing manufacture requested. Not illegal to under label hp rating, just over labeling them.
