Answer

Hello,
Flush out the carb, much of the time oil fills the carb too.
If the cyls were oil filled it will take time to clear out before you'll attain a burnable mixture, it may help to take some carb spray and spray in the spark plug holes and turn over to help flush oil out.You may need to do this 2-3 times. once you get running change out the spark plugs as they may likely be fouled.

you mean starter fluid or?

Accepted Answer

I don't recommend starting fluid.
Please use carburetor cleaner it will do a better job and is safer to use.

Info Request

Sorry to hear your still having trouble. I can't imagine the problem to be anything else other than the oil if it was running ok prior to this.
I know you've probably checked but I want to mention the kill switch to be sure the lanyard is in run position.
