Question about Mtd Garden

Open Question

MTD 8/26 snowblower runs for 5sec then quits.

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.

    Thanks, Jerr. Your solution was spot on. Too bad I couldn't use the snowblower any more this eason, but I should have no trouble with it next year!

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!

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

Start snow blower runs for 3 min. and starts to over heat checked oil its ok then stats to shut down like its not geting oil


Why do you say its over heating .Runs for 3 minutes the oil is OK .
Do you understand how the choke works .
bacsicly you prime the mechine in cold condutions 3-4 pumps choke to max throttle at 3 /1/4 .
Start backing off the choke after 3-to4 mins .
The choke shuts the fresh flow down to the engine in cold condutions ware it needs more fuel then air to run.
When the engine starts to get hot it can't run with out fresh air to mix with the gas it won't run anymore because there is to much gas and not enough air
Its simple fool prof will work everytime if you adjust it right

Mower starts after priming, then quits. new sparkplug, air filter etc. cleaned bowl still no luck. cleaned out orifices in bowl screw. nothing. Suggestions?


Evan though you cleaned the bowl, the float isn't "floating" correct in the bowl to raise the needle for gas to flow into the carb. The float and needle can be replaced. When you prime an engine the gas shoots straight to the carb. As when the engine is running the floating goes up and down to raise the needle for gas to flow.

Is there a choke setting and throttle setting for best results in getting the MTD yarde amchine started?


Most of the small outdoor power equipment that I have used takes the following to start:

1. Prime 6-8 times, or whatever the manual calls for.

2. Choke the carb to full choke.

3. Pull starter rope. It may sputter and die.

4. After it sputters and dies, put the choke on 1/2. Pull a time or 2 more and should start. Run like that 10 seconds or so, then take choke all the way off.

Try this sequence. Pump up the fuel bulb until it gets hard. There should be something equvilent to a fast idle setting, then hold in the primer(electric choke) and finally turn the key and crank. When it tries to start go easy on the electric choke. You may want to see if the electric choke moves freely.
