It was running fine. I drained the oil and added 2 quarts of 10W-30 and it blew up in 1 minute. It started smoking as soon as I started it too, which it wasn't doing before.
A little? Three pints is what the Operators manual calls for. That'd probably been perfect.I think it was a little over filled. I think 1.7 quarts would have been perfect.
It's been my experiance that engines usually run fine right up to the point that they break a rod. Then not so much.rods dont break suddenly for no apparent reason, especially not on an engine that previously ran fine.
