Small Engines (Lawn Mowers, etc.)/Toro 826 snowthrower issue


QUESTION: Model 826 Toro # 38150
B&S type 0989-01
Problem: Initially on start up all is well. As engine warms up after making a few snow passes in my driveway the problem rears its ugly head. Under load (throwing a good amount snow) engine seems to starve for fuel, looses power and wants to stall....sometimes it will if I am not quick enough to prevent it from happening. Motor with no load runs somewhat smooth but with occasional flame shooting out of the exhaust. Choke is set midway to maintain engine running smoothly. Appreciate yor response back.

ANSWER: It sounds like the engine is running lean.  There are 2 circuits in the carb...low speed which is where the engine runs most of the time and the high speed circuit which is only open during heavy engine load.

There maybe some partial blockage in the carb high speed circuit.  

Have you removed, dis-assemlbed and cleaned the carburetor with compressed air from an air compressor?  


---------- FOLLOW-UP ----------

QUESTION: I kinda thought it was related to a carb issue. Can you please provide me some guidance in the disassembly & reassembly of the carb and resetting the needles;etc. Note: I do not own a tach to set any rpm levels. Will I need to purchase a rebuilt kit in case I damage a gasket;etc.? Also should the spark plug be replaced? One final point would it be easier if I ran some carb clearner in the gasoline instead of doing a carb overhaul?
Thanks for your help!

What is the engine model number?  It will be a 5 to 6 diget number.  The type is 0989-01.

I would not buy a tachometer...not worth it for a one time use.

You may need to buy a rebuild kit.  I would at least price a kit and check to see if you local Briggs dealer has it in stock in the event you need it.

We always replace the spark plug...we see a lot of spark plug failures.

I doubt carb cleaner added to the fuel will fix the problem.  We do recommend using a fuel additive for all small engine fuel tanks and your small gas cans as well.  Using fuel additives will help maintain the fuel quality.

Send me the engine model number so I can see which carb you have.

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.
