Oh my. I thought he was saying that the motor was not getting the oil that it needed.

Damn my eyes.

I guess it would have been too difficult to state that the model is a C150TLRU.

If that is what it is.

Thinking about it now, it might be an oil injected version that has been converted to premix.

Providing the model of the motor seems to be a very difficult task.

I agree.
not sure why people think we all know what motor they are talking about without them telling us up front in their posts

Luckily I started reading before drinking a few cool ones today.

my mind is a little sharper when I do that some days.

Dang it is hot in the middle of the day here in tx .
Had to retreat to the AC
