Here is a new video for cleaning out the main jet without removing the carburetor - th-cam.com/video/iWF4P70rtVM/w-d-xo.html.
Ok, i have the exact blower, had it for 15 yrs, the thing surged just like yours is, i finally fixed the problem, & it was not a dirty jet like i thought it was, the problem is yr Pilot Jet, remove yr Pilot Jet , their is a little brass pc. inside of the black plastic jet plug, take 1/16" drill bit, & attempt to drill yr pilot jet out, it will automatically spin because you wont be able to drill it out, at that point, push the brass pc completely out, Remove the Whole Brass Pc. it is ok, & i promise you just fixed yr problem, it will not be too rich or nothing bad, you wont have to run with the choke on anymore, Guaranteed 👍, you just fixed the problem, they put such a small pilot jet in there for California emissions laws ....IT IS NOT A DIRTY CARB, IT IS YR PILOT JET, REMOVE THE WHOLE BRASS PC.INSIDE THE BLACK PLUG PILOT JET, THAT WILL FIX THE SURGING !!!!!
Great comment, I believe the idle jets are designed to run the engine very lean under no load so it can pass the EPA requirements. Under load, the engine should not surge if the main jets are clean. I should take it apart some day to get to that idle jet on the top and enlarge or remove the metal piece as you mentioned. For now, I am fine with it surging at idle.
Thank you for thos video. I drained my gas tank and I will attempt to drain the float portion by the carburetor. Happy to see someone who has the same exact one I do
You can also remove the main jet and clean it. See my other video th-cam.com/video/iWF4P70rtVM/w-d-xo.html.
Sea Foam works, but you have to use in all the time. Always mix it in every time you fill your gas can. Make sure you have a well sealed gas can. I have been using Sea Foam for years with very good results. Good luck.
Thanks for the info!
can i mix seafoam with gasoline and how much should i do?
@@lamantino5 Greetings, Lamantino5. This video will help answer your question concerning how much Sea Foam to add to fuel. Hope this helps. th-cam.com/video/bMAFQDknyUE/w-d-xo.html
@@lamantino5 Mix Seafoam 1 oz. per gallon to keep your carb clean and your engine running smooth.
According to Sea Foam, when dealing with a dirty carburetor, you can use Sea Foam up to a 50/50 mix. If available in your area, I highly recommend using non ethanol fuel. Ethanol is the reason for dirty or clogged carburetors. When left in the carburetor bowl in the off season, the ethanol absorbs moisture and as the fuel in the bowl evaporates during storage it can cause corrosion and, in some cases, jelling. It is best to close the fuel line coming from the tank and drain the float bowl completely before storage.
I wish I could buy non-ethanol gas in our area. Mixing ethanol with gas leads to all these carburetor issues.
The best way is to remove the carburetor. There is a jet on the top of the carb you cannot get to without removing the carburetor. If you do not clean this jet all is lost because you will have engine surging and the machine will not perform properly.
You are correct about the jet on the top that makes it surge during idling. Under load the main jet is the one that takes over and in my case I was able to get it running again by cleaning this main jet (th-cam.com/video/iWF4P70rtVM/w-d-xo.html). Manufacturers size the idle jet too small so the engine runs lean to comply with the CARB regulations and it is a pain to get to that portion of the carb.
Thanks 🙏🏻
You’re welcome 😊
Hello, Since it's the end of winter, I ran my Craftsman snow blower until the gas was completely gone. Then I added ethanol free gas and ran it for my 5 minutes. Should I leave the snow blower in the choke position until November when I start using it again? Should I add sea foam to the Ethanol free gas?
Ethanol free gas will not degrade and clog like ethanol added gas from moisture. You can leave it without choke till next winter. Seafoam is not needed as well but does not harm to put some in. I wish I could get ethanol free gas for the small machines in our area.
@@DIYWithIndi thank you!
Did the seafoam resolve the surging issue? Mine is currently surging and I not in the mood to disassemble the carb to clean it.
Seafoam will clear out some. I just cleaned the jets without removing the carb, see this video - th-cam.com/video/iWF4P70rtVM/w-d-xo.html.
@@DIYWithIndi ok, thanks.
You can put antiseize on the spark plug for an ease removal))
Makes sense. Thank you for the comment.
You shouldnt tighten plugs to the point you cant crack it loose on your next maintenance, im a mechanic, luckily havent had the issue, but people have broke plugs in blocks trying to remove over torqued plugs
Indeed, the absolute max torque spec I've seen for a spark plug is like 35 lb/ft.
hi question for you I have the same machine but in that prime not get gas how I fix that
Check my other videos th-cam.com/video/iWF4P70rtVM/w-d-xo.html or th-cam.com/video/KiXZlO9NATA/w-d-xo.html. Usually these machines have problems with gunk in the carburetor from ethanol in the gas sitting in there for too long.
Seems you r good knowledgeable about this , so , do u think it will be good idea to use seafome with gas fuel , and use , so always stay clean carb ? Thanks
Seafoam or Sta-Bil will help to stabilize the ethanol in gas for short periods from moisture absorbed by ethanol which degrades it and clogs up the fuel jets. I drain the gas in the snowblower if it was not used for a month since snow blowers are prone to more moisture than any other small equipment. I also recommend draining the float bowl in the carburetor (see my other video - th-cam.com/video/KiXZlO9NATA/w-d-xo.html).
Thanks for very valuable information. But seems , video is not complete. Do u have other part ? Please, help .
This video might help you also - th-cam.com/video/KiXZlO9NATA/w-d-xo.html
Thx
Any time
My Craftsman mower starts fine with the choke on, but when I turn it to run it shakes and shuts down. It started fine about a month ago. Can I just add 4 oz's of Seafoam to the gas tank and then run the engine until the gas+seafoam is gone? The gas is only about a week old.
You mentioned mower, not snow blower. Check the air filter and replace it if too dirty. The carburetor may be too dirty to clean with Seafoam. You can try cleaning up the carburetor float and jet - th-cam.com/video/iWF4P70rtVM/w-d-xo.html though this video is for snow blower.
@@DIYWithIndi Thanks, I did mean snow blower not mower
After initial start on full choke, switch to half choke and run until warmed up. Switch to run after warm up is complete.
@@jerryhicks5940 Are you saying add the sea foam to the gas tank and then run on half choke until it warms up?
@@aoppen13 Nothing to do with the sea foam. Just normal start up procedure.
I have power smart snow blower, is there any air filter, if you know ? Thanks
I was wondering the same thing about my craftsman. Apparently they don't have air filters coz blowing snow would clog them!
no
Thanks
Did it ever stop surging after the seafoam?
These carburetors are made to surge when idling but it should not surge under load. Check out my other video th-cam.com/video/iWF4P70rtVM/w-d-xo.html to clean out the main jets if yours is not working well after seafoam treatment.
Well, what was the outcome?
I have another video th-cam.com/video/KiXZlO9NATA/w-d-xo.html on fixing the snowblower which will not start due to old gas residue clogging the needle valve in the float bowl. This was the next step of using SeaFoam before I put it away. I think this helped in cleaning up the carburetor and it runs better.
I grew up in a small town, I still soak my parts and gasoline.
You probably have access to ethanol free gas. That is what I need for these small engines. Those are not available in our area.
Still runs terrible
It needed a carburetor jet cleaning - th-cam.com/video/iWF4P70rtVM/w-d-xo.html.
