Put 98 type fuel in the Spitfire Pope mower instead of normal 91...now will not start? Should I just empty this fuel out?

SOURCE: oil type

I don't know what a pope spitfire is, but the post indicates it's a pushmower -- in that case, I would use 30 W non-detergent.

You may have struck the blade while mower, hence shearing of the flywheel key. You'll have to remove the pull cord casing and then the flywheel. Any dents or twists in the key will throw your timing off. The spark plug may have spark but now it doesn't fire when you need it too when the piston is on the compression stroke. Check this before checking anything else. You could try putting a spoon ful of gas in the plug hole and then replace the plug, if it doesn't start. More than likely i'm right. If the plug has spark on it that is. Good luck.

Caren,
Drain the fuel completely if it is older than 1 week. Make sure you undo the bolt at the bottom of the fuel bowl to ensure all old fuel is drained. Refill with fresh fuel (premium unleaded) and try again. If it still does not work then remove the spark plug and rest it on the metal of the mower while still attached to the silicone ignition wire. Have someone hold the cut out bar to the handle (as you normally would to run the motor) and pull the cord. You should see sparks being emitted from the spark plug. (Make sure there is no fuel nearby) If you cannot see any sparks then replace the spark plug with a new one and repeat this process. If you still cannot see any sparks being emitted after attatching the new plug to the silicone wire, resting it on the metal of the mower, and pulling the cord to start it as you normally would, the mower will need to have the resistor and capacitor checked by a professional repairer as no spark is being generated.

Good luck.

typical pope
spark plug type not mentioned in the user manual
the owner is expected to keep the original plug and buy the same one every replacement


luckily spitfire 40 use a briggs and stratton 4 stroke
so not too many variables
take the one fitted in it with you
could be any equivalent to a cj8 to J19 with a short thread

Another, possibly simple fix, is the float inside bowel could be stuck in the fuel shut off position, or closed. When there is enough fuel in the carb, it is the job of the float valve to stop more fuel from entering the carb. If the motor stays off for a long time as in storing mower through winter, there is a tendency for the float valve to stay in the closed position. To check, remove bowel from carb. There may be some small amount of fuel escaping from bottom of bowel. If fuel ceases to flow out, and you are sure the fuel tank has plenty of fuel, then it is a good guess float is stuck in closed position. Lightly tap on float until fuel starts to pour out then re assemble bowel to carb.

Might be a good idea to have a pair of locking pliers handy to shut off fuel flow from tank so you do not waste fuel trying to thread jet screw back into bowel.

Hope this helps.
