Okay, so I'm showing my ignorance here, but how do I get the oil out of the crankcase? Is it as simple as pulling the drain plug under the dipstick?
FWIW, I'm aware of the issue re not laying it down the wrong way. Found this out the hard way when I first took delivery of the engine, but that was two years ago and it ran okay (not great) last year. I do not think it was laid down the wrong way since then, but perhaps I'm mistaken.
Thanks for the help!
IIRC, I think you are right. I believe there is only one drain plug
on the upper motor housing, nothing else to drain. If it runs I doubt
that the pistion skirt is broken, no other way for the oil to get into
the upper part of the motor except by blowing back through the
crankcase breather, I think. Again, drain the crankcase, and then
remove the spark plug and turn it upside down to drain any remaining
oil iout of the combustion chamber. Don't overfill with new oil. Let us
know what you find, be interesting to know how much oil in total
you drain out.
