Briggs 8hp only runs on full choke

[Westbrooklawn]

Just cranked up my little wonder blower for the first time since early spring. I started o.k. but will only run with the choke in the full closed position. Runs great with choke closed, but when I open it it stalls. Any suggestions? It was working perfectly fine when I put it away in March.

the carb is not supplying enough fuel.. so when you restrict the air you are getting a richer mixture to keep it running....

if you have any mixture screws you can try slightly adjusting them... otherwise most likely you'll have to pull the carb and clean it out..
