One possibility is that the engine is running too rich. When you shut the engine off with no spark present the excess fuel present from the last couple cycles is flooding the engine. This would dissipate after time. Try the idling screw first ajust until the engine is about to cut out and then turn it about 1 turn back and see how it runs.You could also adjust the Pilot screw a tinybit toward the leaner side also. If this doesnt help then the float could be slightly sticking. Of course it could be some kind of screwy grounding problem. Hope this helps.
I have a 14.5 Briggs and Stratton engine on a Ranch King riding mower that will not start. After spraying starter fluid into the head, and air cleaner it fires for a second, but will not run. It is getting gas.....coil??? or something else?
Briggs has a rudimentary wiring diagram for the operation of an electric start engine. see the link below.
It is the whole assembly containing the pull start (if applicable) or the metal or plastic shroud surrounding the flywheel (it spins when you start the engine ).
Try 32 thousands, to start, depends on how much compression the engine has at this point.
bad gas, dirty carb needs new sparkplug. youtube has repair vids on how to do what. user (davidsfarm) has great tips
dirty fuel filter or water in the bowl of the carb
Might be in your ignition : lose wire, bad switch : when it won't start check for spark .
Because its a pos I have a brand new one that won't start.
Clean out the carburetor with gas, the reason it wont keep running is its not getting enough gas through the carburetor.
4.5 mower will start and run for two seconds
Total capacity is 48 ounces if it has an oil filter on vertical shaft engines. Drain the oil change the filter and add 42 ounces. Start the engine and run for 30 seconds. Shut down, wait 30 minutes and check the level. Add as necessary to reach the full mark. Do not overfill. I highly recommend synthetic oil in an air cooled engine.
