B & S Intec 20 hp engine problem

3 year old B & S 20 hp engine on Scotts riding mower has started missing badly on one cylinder. Have replaced both plugs, checked the firing and its good. Seems the one side that is bad is not getting the fuel to the cylinder, plug is very clean and dry. I can pull the choke out part way and the bad side will come in. This all seems to be a fuel problem, please someone out there help. Thanks'

Hello Booker!

Sounds like you need to remove and clean out the carburetor. Another possibility is a crack in the intake for that cylinder, or the bolts could be loose where the intake bolts to the bad cylinder, or the gasket could be leaking/missing.
