Where did you previously say anything about bad gas?
Get all of that gas out of there before you burn your engine up. Bad gas will burn very slow and will still be burning when the exhaust valve is open and even after the exhust valve is closed and it will keep burning until it is gone. At times it can be so bad that it is still burning when the intake valve opens.
Do anything it takes to remove bad gas. Do not strat engine again.
