15.5 Briggs I/C issues
Just picked up a 2009 Bolens lawn tractor at garage sale recently and have had a few issues with the engine. (Which I expected...) it's started up and ran fine drive it around the yard about 15 minutes, parked it and told myself that was a good deal! The next day in an attempt to mow, it ran about 10 minutes max when it lost almost all power in the engine. I checked the oil, which was about a quart over full, and also noticed oil in the breather before the carb. I did a little research online and ended up replacing the head gasket as we'll as an oil change. Put everything back together and the black smoke had stopped but the engine sounds horrible when I move the throttle higher than idle...this is where I am stuck now. The engine is a briggs 15.5HP model number 31A607 Type 0741 B2. Any help would be appreciated so I can now again!!
