Good - you might be surprised how many make that mistake!

Assuming there is no smell of gasoline in the oil, I'd start with a compression check.

Ya, agree with Wintersol, that's what I was getting at. Poor compression/blow-by will do that. A compression tester would be handy if you have one.

I noticed oil was very thin so I drained and will put in some 10w30 when new filter arrives and see how that does. Thanks for all the help. We will see.
