Murray weed trimmer won't start, has spark and getting fuel

I posted about this a few weeks ago...have a Murray M2510 trimmer. Worked in July, next time I went to use it a week or two later it wouldn't start. I took the carb off and cleaned the screen and it ran once, then after that it would pretty much fire off the gas from the primer and then shut off, and eventually just wouldn't fire at all.

It was recommended to replace the carburetor so I bought a new OE replacement and put it on tonight, and it still won't fire. I tried it a few times and pulled the spark plug and it was wet, so it's definitely getting gas. I checked the spark with the plug out and it's also getting spark, so what is the issue? I really didn't want to have to replace this trimmer after less than two years but it's looking like I'm going to have to unless I can figure this out, it's not making sense.

If the plug is wet, that's not a good thing. It's flooded. Either the carb is leaking, the fuel lines aren't connected properly, or there is a bunch of fuel in the crankcase from the last carburetor.

What do I need to do to remedy that problem?

It might be flooded as it's been primed so many times trying to get it to start.

My answer would be..make sure the plug is firing blue..not red..red is to weak to crank it..if its blue fire check the flywheel key..some flywheels are made with the key on it..some aren't..sometimes it will fire but also fire out of timing..if that doesn't work for you..may be no good..hope this works..good luck..

It's definitely making a blue spark, I checked it with a spark tester and with the spark plug connected.

Where is the flywheel? it has this stupid plastic case around the engine and I can't see where anything is.

It is very unlikely you sheared the flywheel key unless you hit something to stop the engine abruptly. With the spark plug out crank the engine 20-30 times to clear the cylinder, pour 1 teaspoon of fuel in the cylinder reinstall the plug, now while holding the throttle full open no choke try to start it. Have a good one. Geo

You guys rock, that worked like a charm. Took a few pulls but it fired up, ran great and smooth, better than it was before. Thanks!
