This motor has oil injection but when I bought it the original owner said it had broke or didn't work or whatever and he just mixed the oil in the gas tank. I seem to remember him saying 50:1. Anybody know if that is correct? Know a way to find out for sure?

Also, at idle, it seems to smoke a bit not when it's running. Should I pull the spark plugs to see if there is a lot of oil on them? Would that tell me anything? Thanks!

50:1 is correct, the engine smoke is normal and yes all 6 plugs should have a lil oil on them.
