Hi all,
I've been lurking for a couple of weeks - looking forward to being a member of this community!
As a housewarming gift, my grandfather gave me his Craftsman mower - the 37719 walk-behind with the Eager/Tecumseh 6.75 hp engine. To my knowledge, the unit's probably five seasons old. Other than blowing a ball of smoke during startup, the unit seems to run well.
Let me say that although my grandfather is my idol and as a man I've modeled myself after him, I think he may not be much for mower maintenance.
He changed the oil at the beginning of this season with some kind of 30-wt oil. Changed the air filter too. As the oil was pretty dirty after around 7 hours, I changed it again with Havoline 30wt. Drained it again after 1.5 hours, and the oil looked like this...
After 1.5 hours!
What's giving the oil this color? It's not sludgy at all, just opaque, close to the color of pencil graphite. Am I still flushing out wear metals? Did I get water in the carb when I washed the mower?
Any help with this mystery is much appreciated. TIA,
miker
