Please help I’m Stuck It’s been 5 months

^^^ Sorta like above. I have had some pretty much woreout slants that have sat for years, and compression very bad. So I pulled the plugs and squirted in good amount of motor oil and marvel mystery oil mixture, rolled it over several times, let it sit for a while. Why don't know. I then poured quite a bit of motor oil down the carb, I mean poured. How much? Don't know. Cranked it over some where the oil got down into the cylinders Then I cranked a bunch while I hand feed it some gas. The oil gave it gas till it started and run. I forget the compression figures but there were low. Always started and run thereafter. Not strong but ran.
I ain't fancy lie AJ I have no fire "extinguisher!" ( That's how AJ spelled it!!)
