Yard Machines B+S 163CC white smike on startup

[hardcore302]

Whenever I start my yard machines briggs and stratton 163 cc powered mower (no change oil system) it blows white smoke for a few seconds. I change the oil, air filter, and plug at the beginning of every season. I throw a few dashes off mmo into the gas at every fill up. Is it just getting old or would the mmo blow some smoke? Thanks.

Pretty much a throw away machine I wouldn't worry about it keep it full probably run for years.

If no other symptoms run it like #318FAN says.

I had a similar issue with my B&S and it was the oil was a little over full. Moved it to middle of stick and it’s been good?

I would make sure the oil isn't over filled, and stop adding MMO to the fuel.

How many hours on the engine?

What weight oil are you running?
