What would cause black smoke and oil to shoot out the front of a push mower?
I have only used the mower 5 times if that, a Briggs & Stratton Model 90000 E Series 550e. I noticed that it started doing this the next time I went to mow after I had it on its top to clean out the debris from underneath. I have cleaned other mowers this way and never had this issue. If this is the problem is there an easy remedy or will it have to be taken in to be repaired?
