Snowblower back fires and stalls out.

Model 247.88790 will run and throw snow but starts to back fire and stall out. This problem happened last year and during the fall I took carburetor off and totally cleaned throughly. Float looked good and after I reinstalled carburetor I ran it through 1.5 tanks of gas. Thought my problems were gone until it stalled out at end of my driveway during the first use. Its getting gas to carburetor. Could it possibly be a coil issue? If it is what degree of difficultly is it? If you don't think it is a coil issue what could direction would you point me in?

Backfiring is normally traced to one of three basic faults 1) running to lean, 2) incorrect timing be it valve or spark, 3) inlet valve not seating correctly or partially burnt out. From what you describe I would first suspect lean running caused by a partially blocked orifice in the carb. I know you cleaned it last fall and tdo it again is a pain in the butt but any gas left in the bottom of the carb, even if the engine was run 'dry', will deteriorateand gum up the works. It is what I would try first, should that not work we can move on to the other possible causes. Good Luck.

Thank you for your question.

I am sorry you are having a problem with the snow blower. I think Biguggy is on the right track with running to lean. To verify this I recommend turning the choke on a little when the engine is running. When you choke the engine, it delivers more fuel and the engine will smooth out. To cure the problem I recommend cleaning the main jet in the carburetor. You will need to purchase a can for carb cleaner from the local auto parts store. Then click on the following link to watch a video on how to clean the carburetor.

The engine is not the same but it will give you an idea on how to do this.

Please use extreme caution when dealing with fuel.

Then after you have cleaned the carburetor, start the engine and slowly turn the choke off.

Please let me know if you have any other question on this problem.
