Thank you for asking your question on JustAnswer. From the information you have provided I will say that the carburetor is the problem. You might try using a carburetor cleaner to correct the problem. Often things can get in the carburetor that gasoline and most spray cleaners cannot remove. In that case a product like Berryman's B9 Chem Dip. or CHEM-DIP<SUP mce_serialized="626"> PARTS CLEANERS is recommended. Use caution and follow the direction when using this cleaner. The carburetor will need to be disassembled and dipped in this acid based cleaner. It will clean the carburetor like no spray cleaner or gas additive can. Once the carburetor is clean I would recommend putting a carburetor kit to insure trouble free operation. The problem is definitely fuel related.
Thank you for your answer. Your diagnosois makes complete sense. At the beginning of winter I made the stupid mistake of grabbing a mislabeled gas can (labeler 40:1) and prepared a fresh mix. My Toro snowblower requires a 32:1 mix. After trying to run the snowblower unsuccessfully, I realized my mistake. I then emptied the fuel tank, prepared a fresh mix at a 32:1 ratio. I have tried to run the snowblower at least a dozen times since (hopefully burning any bad mix), but it continues to die after starting.
Unfortunately, I am not very handy, and would not know how to disassemble a carburetor. The Toro model is about 25 years old, and I lost the manual over this past year. Is diassembling the carburetor a simple task or one that I should trust to a mechanic? Thank you for your help.
I would suggest that it would be best to have the carburetor cleaned at a small engine repair shop. The cleaner I suggested is rather expensive. It can be used over several times but it does not usually make sense for a consumer to by it since it will go bad before it is used enough times to be economical to purchase.THey will likely install a rebuild kit in the carburetor after it is cleaned. This will insure that the engine will start and run correctly.
Thanks Edward. I appreciate your advice. I was hoping to be able to avoid the hassle and wait time (they usually take a week to fix things) of going to the repair shop, but it makes the most sense. I am totally satisfied with your answers and with your promptness. This is a cool service.
Best to you over the holidays.
