Briggs and stratton engine runs rough, Twin II 18HP

SOURCE: Briggs and Stratton 20hp twin cylinder runs only with full choke

Had one on my saw mill had this problem as well Try pulling bowl off bottom of carby as the float can get **** with old fuel especially ethanol fuels as they attract water bowl is normally held on with one center screw on bottom of carby. Note always turn fuel off and let engine run out of fuel as this stops goop from building up in carby

First thing to do is pull your dipstick and check for broken or missing O-ring also as you pull it, look to make certain that it was seated properly and all the way locked. If either condition exists, you will be leaking into the crankcase which will cause your symptoms

SOURCE: oil appearing at exhaust, smokey, briggs and stratton lawm mower.

You will need to replace or clean the air filter, and probably the spark plug. Do not operate the mower for some hours to allow the oil drain (inside the engine). Check oil level and fill it if necessary. Some oil remaining in the exhaust should be burnt next time the lawnmower operates.You will see smoke at the beginning, that will be normal (burnt oil). Hope this helps!
