Thanks, yes have put in racing oil that already shows it has zinc (no synthetic). Changing the oil filter was kind of a bear. Yes, just got it delivered last week - thanks! The weird part is that when engine is warm and I go to start, it takes several times to start (battery good). Then after 3-4 tries it comes to live and I pump the gas a bit to get it to rev a bit then idles down. When I put into D, it stalls. I don’t know why. Thoughts?
