Question about Briggs & Stratton Garden
Murray Wide Body Riding Lawn Mower 14.5 HP 40". The problem I notice was after I mowed the lawn and mower cool off. I noticed a odor it was gas in the exhaust. So I took the exhaust off and got the gas off. I check my oil dip stick I notice it smell like gas. So I drain the oil out of the mower. There was gas there too. I change out the gas filter and oil. It starts and runs. I check the oil dip stick again it looks ok but still not sure is gas is still going to the oil. I never had this problem before and wondering why the gas entered the exhaust system?
The little solenoid on the bottom of your carb is letting gas flow while it is not runnung.therfore gas gets into your oil.About an 80.00 part..or you could just turn your gas valve off when your done mowing.but still you would have to eventually replace that part.hope this helps

Sounds like the needle and seat need to be replaced. It is leaking and not shuting all the way off and it will fill up and drain back into the intake exhuast and into the oil. Try a new needle first and if still the problem then replace the seat.

If the rings are worn and beginning to "blow by" sometimes it will make the oil smell like gas and turn coal black. In addition to making the oil yucky earlier than normal it thins the oil making it blow through the engine via the rings.
On multi cylender engines if one chamber is not firing it will send its unburned fuel into the exhaust but you would notice that the engine sounds funny and produces less than half the power it used to.
