Have you tightened it up enough, also is there a rubber seal between the housing and the filter and is this correctly in place.?

SOURCE: 6522sh husqvarna mower leaks oil

no solution other than have the seal replaced its cheap part but the labour content makes it cost.however the cost of a damaged engine & shaft make the repair worthwhile. overfilling of oil can cause this just check if the oil sump breather is clear as this can cause excess pressure on the seal.

SOURCE: My mower will start but not run

if the filter is a sponge filter then it's suppose to have oil in it(helps trap dirt) and if your getting gas out of the muffler then the engine is flooding when you try to start it..good luck

SOURCE: lawn mower wont start. changed air filter, spark

Does it turn over? If it does, what happens? Does it sound normal when its cranking? I need more information to help. Is it a push mower or riding mower? Does it start by key or pull start?

SOURCE: husqvarna 7021 kohler 173cc looks like its leaking

The carburetor probably needs cleaning -- the float is sticking.

I am losing power going up hills and smoke comes out in front of mower

check for excessive oil in the sump (carby needle and seat allowing fuel to drain into the sump past the rings when standing for a period of time )
what you describe is indicative of excess oil and the oil ring cannot handle the oil control
this in turn affects the air/fuel mixture and makes it hard for the engine to run

Change you oil and while you are at it change the filter. Do not run until you have completed. You risk engine damage by loosing too much oil while running it.

Carb blows black smoke and runs bad but run good with no air filter or with a new filter

The old filter must be clogged. So if it runs ok with a new filter do you still have a problem?
