Starting an old engine ....

I'm with Moper, except I would mix gas and 2 stroke oil at like an 8:1 ratio, and run it off that.
Fill the float bowl with a small funnel or a soda battle with a small hole in the cap vie the bowl vents. Just like a new engine, the best way to start it is QUICK! Then, dont let it idle, keep it somewhat revved up to get the lifters spinning and the oil flowing.
And don't put freakin' tranny fluid in an old engine..........
