Small Engines (Lawn Mowers, etc.)/john deere snowblower


QUESTION: hello I have a john deere 826 snowblower that will not stay running when I engage the spits and sputters and finally dies...I think its a dead man switch but I have never messed with

ANSWER: If it were a safety (dead man) switch the snowblower would shut-off quickly...not spit and sputter.

It sounds like you have a dirty carburetor...most likely the high speed circuit.  

Does the SB start easy, idle and run with out the auger being engaged?  Does the SB continue to run if you try to just drive the machine, no auger?

Do you have an air compressor?

Let me know.

QUESTION: Yes runs fine but like I said it only does it when I start to engage the auger......any ideas?

Is something stuck or binding in the auger assembly?

An easy tip to verify if it is a safety switch problem is to remove the engine shroud, the sheet metal that contains the pull starter, to access the ignition module.  With the cover removed you can see the ignition module and just dis-connect the small wire connected to the ignition model.  This will dis-connect any and all of the safety switches but you will not be able to shut off the engine with the on/off switch.  Just use a pair of insulated pliers and dis-connect the spark plug wire to shut off the engine.  This will tell you for sure if you have a safety switch problem.

You can actually dis-connect or isolate the ignition module without removing any parts.  You just have to find where the engine shut-off wire is connected to the engine.  Usually this is near the carburetor throttle and the on/off switch.  Just dis-connect the wire that is connects to the ignition module...the wire entering the engine shroud.  You can verify you have the ignition system isolated by trying to shut off the snow blower...if the on/off switch will not shut off the engine then you know the ignition module is isolated.  Just keep the insulated (rubber handle) pliers handy.

Let me know if SB will run with the auger engaged with the ignition module dis-connected.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
