Why does my Briggs and Stratton backfire through the carburetor


Ignition timing. Possibility of keyway in crankshaft being damaged. Intake valve. Check engine compression and intake valve clearance. Lean mixture. Check torque on bolts holding carb and intake.

What causes a lot of gas in oil on 8.5hp B&S


This would be caused by a sticky needle valve on the float in the carburetor.You have three cures 1. remove and clean the carburetor internally. 2. replace the carburetor with a new one. 3. or most simply buy and install a fuel shut off valve and turn it off when not in use. make sure you change the oil 1 4 ID LINE GAS FUEL SHUT OFF VALVE TECUMSEH BRIGGS

How tocheck timing onbriggs stratton model44577


The timing is fixed, if you suspect the timing is off the only adjustments available are the .030 clearance from pickup to flywheel and the shear Key that positions the flywheel on the crankshaft. You would also want to make sure your valve clearance is .030 as well, the issue sounds like a valve leaking, a dead cylinder or mal adjusted valve clearance causing the exhaust valve to hang open just a bit.
