I'm stumped with the carb on my B&S 14 hp engine. It was running fine, then it stopped. Checked fuel line, no clogged filter. Took of solenoid, bowl, etc. Everything appears okay. Cranks it over and over and it won't start. Poured some gas after removing the air cleaner and it catches, runs for a few seconds then dies. Also replaced spark plug. Still can't get it to run. I'm going to try seafoam in the gas tank. Don't want to take carb apart.
Hmmm. What do you guys think?
The fuel bowl after fire solenoid may be defective. Check it to see if the plunger is activating with the key switch. It should retract with the key on and go back out with it off. If not working, there is your problem. The plunger stops fuel flow to the main jet. If you don't plan to replace it, you can snip the plunger off and it will run. Just be aware that the mower should be idled down for a about 30 seconds before shut off or it will do the after fire through the muffler.
Thanks to everyone for the advice. I will look at the solenoid first to see if it's working. Might have to take the carb apart to check for a sticking float and needle. Just got a cool front that came it, making pleasant to work outside. Wish I could be mowing instead of wrenching.
Okay guys, it's middle of October and we finally got rain in South Texas. Murray still won't start. New spark plug, cleaned out the gas tank, new fuel filter, new battery. Cranks and cranks and won't start. Grass is getting taller. Spark is visible at the end of the plug.
Carb problem or coil needs replacement?
Did you check out the fuel solenoid as suggested above? Got fuel, got spark, remove the cooling shroud, remove the flywheel screen, remove the flywheel nut or bolt, look down the keyway to see if crankshaft and flywheel keyways line up, use pen light. if not sheared or partially sheared flywheel key.
