If it's stuck in the completely open position, it can.
yes. a valve in the open position will prevent compression, thus no combustion.
Then you'll experience frequent low oil pressure issues.
You replace the gas valve.
My brinks locked in the open position. What do I need to do to get it fixed
Blowback into a 91 F150 air filter could be caused by a bad PCV valve. Check the valve for it being stuck in the open position.
Sure if the valve gets stuck open and the flapper get stuck closed.
If by "overloading" you mean flooding (too much fuel), two reasons are (1) the carburetor needle valve is "wide open" or the float is stuck in the open position.
when the piston comes to top dead center or in full up position the valves must be closed if they are open the piston will hit the valve and bend it this usually happens from a valve timing issue by a slipped timing belt or chain. sometimes though this will happen if the valve sticks open from a bad valve spring
In the open position
It could be that the spark need to be replaced. Other reasons could be that the carburetor needle valve is opened too far, or the float is stuck in the open position.
It is possible if it is stuck open, but highly unlikely.
