John Deere 430 diesel starter and solenoid replacement
Make a test lamp with a headlamp bulb.
Connect it on the solenoid output starter lug. Turn the key; does it light ... starter faulty if it does, solenoid faulty if it doesn't.
If starter, give the motor housing a thump with the wooden handle of a 2lb hammer. That may get you going until new brushes are fitted.

Your filter is being soaked with fuel from the carburetor float valve having trash/debris under the seat or jamming the needle valve.
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instrucitons you get with the carburetor kit.
If the mower/weedeater is over a year old, then I also recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.

I have a Craftsman ZT S7500 Mower that runs 5 min. then stops wait 5 or 6 min. it will restart then shut down
My first thought is fuel delivery but could be other.
To determine if its fuel or spark, run it until it fails. Then try starter fluid directly into the carburetor. If it fires and runs for a few seconds then it's a no fuel issue. If it cranks but does not fire, then more likely a no spark issue.
To successfully use starter fluid you need to remove the air filter assembly and spray a one second burst of fluid directly into the exposed carburetor throat and then promptly attempt to start.

Mcculloch 280B gas blower has compression, fuel, ignition, won't start
Remove all fuel. Remove spark plug. Dry out the crankcase and cylinder by pulling the starter several times.
Reinstall spark plug. Remove air filter, hold throttle open and spray a short burst (~1sec) of starter fluid down throat of carburetor. Release throttle and promptly pull starter rope up to 5x.
If it fires and runs a few seconds then it is a fuel/carburetor problem.
If still no fire then more likely a spark or compression problem. Replace spark plug with new proper type and gap. Retry with starter fluid. If still no run then likely either a failed ignition module or poor compression/crankcase leak.
