Question about Mtd Lawn Mowers
I have an older MTD 8/26 snowblower. I prime, turn on choke, raise throttle and hit the electric starter. The engine starts with the choke on and immediately cuts out when I torn the choke off. With the choke on it runs for 5-6 sec. then shuts down. Last time I used it, about a month ago, it started up on the first pull and ran great. I changed the spark plug at the beginning of the season.
Concerning your starter/pull cord problem, what has probably happened is that due to sitting idle for an extended period, the pinion gear had stuck in the down position on the clutch drive.
When you engaged it with power it spun as it was supposed to do but did not immediately spin up into the ring gear.
After you released the starter button and it began to slow down the gear spun up into the flywheel and jammed because it didn't have enough power to turn the engine.
A usually simple fix for this is to turn the engine backward by hand just enough to relieve the tension and the return spring will push the gear back down.
At this point, you can try the electric starter again and it should work properly. If it does not work, you will have to remove the starter and clean and inspect the starter drive on the top of the starter.
Concerning the fact that it would not start, you more than likely have some old fuel trapped in the bottom of the float bowl.
You may be able to remedy this by spraying some carburetor cleaner in the carb while trying to start it.
If it has spark and everything else is in good condition, it will start and run as long as it has carb cleaner getting to the engine so you may need to spray it a few times while it is running on that and sometimes the stale fuel problem will clear itself.
If it doesn't clear up and run on its own without the carb cleaner after 3 or 4 shots of spray you will need to remove the float bowl and clean it and the main jet with the carb cleaner.
Protect your eyes and bare skin while using the carburetor cleaner, it will injure you. Do not spray it on any rubber gaskets or seals, it will swell and ruin them.
Sorry for the "book" I wrote but I am trying to explore as many possibilities as I can to get you up and snow blowing!

Testimonial: "Cured the problem just like you said. Thanks"
For a manual go to mtd.com You will need the model number to find the correct one. As for you problem take the fuel line of where it hooks to the carb see if you have fuel getting to the carb. If you do you will need to remove and clean the carb. Before you remove the whole carb take the bolt out that holds the carb bowl on and clean it this might do to trick.

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, 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.
If the mower/weedeater is over a couple years 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 seat the jet screws and count the number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns they were in/out.
Please do not forget to rate me, Thanks
Good Luck, I hope this helped
