Have 5 h-p B&S motor,model 130202 type 401501 code 90010827 on snowblower. Starts,idles and revs fine. At idle it has a little lite blue smoke that comes out of carb. Looking down into carb a little gas is pooled at the bottom of the intake. When throttled up smoke disappears and the gas is pulled into the carb. Both symptoms don't reappear till throttled down to idle.

Is this a sign of worse things to come??
Thanks to all in advance for their advice.
Merry Christmas

Hello T.J.!

Sounds like the rings might be getting worn. If the engine is otherwise well taken care of, chances are a new set of rings will fix it right up when the blowby gets to be too much. For now, it doesn't sound like it's too bad. It may not degrade quickly and might last several more years before needing work. Make sure the oil stays to level.
