In need of advice. I have a 2017 husqvarna with Briggs & Stratton motor its started blowing white smoke .I have oil on plug and small oil leak out of bottom of head gasket. It was under normal use grass was not high. I have cut much higher grass before. Do I need rings. Plan on replacing plug. Please help

Lets start with the model number information off of the engine. So we can see what you have. With the information that you provided this could be any of about 5000 engines. on about 100 pieces of equipment.

Model 33r777 type 0003 g1 code 150323zd

It is a good chance that you just have a blown head gasket. These have head gasket design that leads to them blowing.
