SOURCE: i have an ariens snowblower,

Hello,
My name is Dane and I am going to assist you in solving your problem.

The first thing I would check is to check your spark plug isn't fouled and then make sure your gas cap is venting properly. If the vent gets clogged, the tank will actually get a vacuum built up and no gas will flow to the Carburetor. The next time the machine does this, loosen the gas cap enough to allow air to get in the tank, and then retighten. If it runs fine, the vent was clogged. You have to clean out the vent or get another cap.

If your fuel is mixed with oil, make sure it is mixed correctly. Too much oil in the mix will cause problems. Make sure you haven't left old fuel in it for a long period of time and gummed those jets up. Sometimes an engine just needs to run with good fuel in order to clean the jets out. If this is the case, just replace the fuel, get it running and work it normal for a tank of fuel if you can. You should see improvement by then.

If it still doesn't run correctly, you will have to adjust or clean the Carburetor. One thing to remember: If your engine has run fine in the past, you probably have a clogged Carburetor. If it hasn't ever ran right, you should adjust the high-speed jet.

If you need to clean the Carburetor, you will probably need to remove, disassemble, soak, and use compressed air to blow out the jets in your carburetor. Pay close attention to how the carburetor is attached to the engine. Make a drawing if you need to or take some pictures. Remove the Carburetor from the engine. Remove the air filter, linkages, throttle/choke cables and fuel line. Remove the mounting bolts/nuts. You will need to disassemble the carburetor as far as possible and put it in some Carburetor cleaning solution. You can get this at any auto parts store. Do not place rubber parts in the solution. Allow it to soak in cleaner as directed, and then blow out the ports and jets with compressed air immediately after you take it out of the cleaning solution. Be careful not to get any spray back on your skin or in your eyes. Reinstall the Carburetor in the reverse order. Replace any worn or torn gaskets or o-rings as you assemble and reinstall it.

If you need to adjust the high-speed mixture setting on your Carburetor, turning the screw out just 1/2 turn or so should do the trick. It is not so hard to adjust the Carburetor, however you do need a special tool that is very hard to get your hands on. They don't make many engines with plain screw heads on the jet screws anymore. The newer Carburetors are factory set lean so they can pass emission standards. If you have a local dealer, they should adjust the mixture for a couple of bucks. If you can adjust the screw, start the engine, allow it to warm up, and apply full throttle. Start backing off the screw just until the engine gets max RPM. That's it. You're done.

Just a TIP: Always mix your fuel with an approved fuel stabilizer. Fuel begins to go bad after a few months and that's why many people have fuel problems in the spring.

I hope I've helped. Thank you! Dane

Hi Kevin
------------------------------------------------------------------------------------------------------------------------
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:
Write down on a piece of paper and or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.
Mark each piece with a awl, or some kind of sharp instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using a very small shot of 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.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line/s condition...after a while they will degrade and need replacement.
Check/Clean/Replace your fuel filter if you have one.
When you remove your fuel lines from the carburetor be sure to make a drawing or take a picture of how the lines are connected to the carburetor.
Also a good time to take a picture for later reference for reassembly.
If the mower is over a couple of years old, then I 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.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or 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.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
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 original position before you started.
Once you have your carburetor cleaned/rebuilt that should solve your problem.

I have a Ariens snowblower deluxe 30 which is a year old. Starts fine and will run. Unfortunatley it is running way to low. I have replace the gas with fresh gas ran it through completely


It is very possible the carbureator needs a cleaning. Moisture can corrode the inner parts of them if left all summer. I find that the fuel usually does not go bad over the summer. I always start my snowblower once a month over the summer and then have no problems when the snow flies again. There was a time when mine was losing power and quitting also. There is a screw on the bottom of my carbureator that needed adjusting. If you are lucky that may be all you need. By turning mine in and out a bit I found the spot where the gas was correct and it worked fine again.

How can you start a Ariens 824 snowblower


Ignition key on, throttle three quarters on, full choke, press primer 3 or 4 times, pull cord. Should cough, maybe start and run rough, then as it's chugging, turn choke to half, then quarter choke, let it warm up slightly, then choke off.

Ariens 2 cycle snowblower runs a short time then stalls.


That sounds like a float problem. When you tip it back it is raising the floats letting the fuel go through the carb. But when back at normal it closes the the fuel feed and thus stalling the engine check the float assembly.
