20hp ohv briggs stratton 1 cylinder engine has oil coming out of breather vent on fuel pump
the oil level is fine just changed it and filter put new fuel pump on. Engine does not seem to be missing and do not smell any fuel in the oil. checked the crank cas vent and it only had a flapper in it but cleaned it also. Engine does not spit oil when first started will do it after about 10mins of running and will occasionaly get a whit puff of smoke on hill side when mowing
