Learn a lesson on bad gas

I agree it could be any combination of things but just the few intake valves are sticking. I was going to try replacing that push rod. disconnecting the fuel line from the intake on the fuel pump and running a hose into a gas container of fresh gas. chances are this won't help anything probably just bent the rod again. That one vale when push sticks open and slowly will return to its position. seems like a tight guide but it didn't do this before.
