My snow blower toro Storm 5024 with briggs & Stratton engine

Customer Question

My snow blower toro Storm 5024 with briggs & Stratton engine will start up perfectly run for about a minute and then blow blue smoke and will almost quit then rev up again for a few moments then start blowing blue smoke and will eventually quit. Some times it will start right back up and do he same thing. I took the carb off and cleaned it with carb cleaner but dose the same old thing. It almost seems like the kill switch or key is shorting and causing that to happen. Any Ideas?

Have you checked your oil to see if it smells like gas is mixed in with it? Also, have you checked your oil level?

Customer: replied 23 days ago.
Oil dose not smell like gas and oil level is a ways above the add line
Expert:  Donald replied 23 days ago.

Thanks for your response. The smoke is likely caused by your too much oil in your crankcase.

Customer: replied 23 days ago.
Oil is fresh and at the proper level
Customer: replied 23 days ago.
Turning choke when dieing and does not help
Expert:  Donald replied 23 days ago.

I misunderstood you. I thought you said "your oil is a ways above the add line".

Expert:  Donald replied 23 days ago.

Did your engine run satisfactorily, the last time you used your snow blower?

Customer: replied 23 days ago.
Add line not full line
Expert:  Donald replied 23 days ago.

I understand now.

Expert:  Donald replied 23 days ago.

There are three small holes in the bolt that secures your fuel bowl to your carburetor. Did you clean these holes?

Customer: replied 23 days ago.

choking the engine when it started dyeing would not revive
Expert:  Donald replied 23 days ago.

Have you confirmed whether you are getting a steady flow of gas, from your fuel tank, to your carburetor?

Customer: replied 23 days ago.
it does
Expert:  Donald replied 23 days ago.

Based upon what you and I have covered, I am lead to believe that your carburetor is at fault, although you have cleaned it. Did you soak your carburetor, prior to cleaning it?

Customer: replied 23 days ago.
No just used carburetor cleaner spray
Expert:  Donald replied 23 days ago.

Did you use compressed air?

Customer: replied 23 days ago.
No
Customer: replied 23 days ago.
When I sprayed the carburetor cleaner through the little holes stuff come out the other side
Expert:  Donald replied 23 days ago.

I believe if you clean your carburetor some more, this will help. I would use a small wire to clean all of the small jets and fuel passages in your carburetor.

Customer: replied 23 days ago.
I can try that what Abby anything wrong with the killswitch part of things
Expert:  Donald replied 23 days ago.

I can tell you how to check to see if your kill switch is shut your ignition down.

Expert:  Donald replied 23 days ago.

Start your engine. Allow it to run until it begins to shut down. At this point, immediately spray some carburetor cleaner directly into your carburetor, to see if your engine will run longer.

Expert:  Donald replied 23 days ago.

If your engine will run longer after you spray the carburetor cleaner into your carburetor, I would say your ignition is not at fault.

Customer: replied 23 days ago.
Ok that should let me know yah . I will try that thanks
Expert:  Donald replied 23 days ago.

You are very welcome! I do hope all goes well for you.

Customer: replied 23 days ago.
