All plugs are, But you should check them yourself again.
ALL gasoline engines have spark plugs. Only diesels don't have spark plugs.
It should try to start at least. It may or may not actually start but you should hear it fire on the 2 good plugs. Why not just replace all 4 spark plugs?
Yes, all gasoline engines have spark plugs.
It is likely that it is not firing on all spark plugs, you should try checking spark plugs and timing, there could also be a problem with the distributor cap or spark plug leads themselves may be worn. Try chacking backwards from the spark plugs.
To replace the spark plugs on your Celebrity requires a 5/8" spark plug socket, short extension and either a ratchet or breaker bar. First remove the spark plug wire then use the socket to remove the spark plug. The spark plugs should have a .045" gap. Replace the spark plug and reattach the wire. Continue until you have replace all of the spark plugs.

Changing spark plugs is pretty simple. Disconnect the battery, remove the wires to the spark plugs from their location, remove the old spark plugs, put in the new spark plugs, plug the cables to the right spark plug and reconnect the battery.
arnt all spark plugs just below the valve covers on all engines ???
No you do not need to replace any plugs at all when replacing wires.
the spark plugs are screwed into the engine block and the top part of them is covered by a single wire, if you have a four cylinder engine, there will be four spark plugs, the wires will all go from the spark plug to a distributor cap and should pull straight off on each end, if you are replacing the spark plugs make sure not to change any of the wire locations
At the end of all the spark plug wires.
