Hello Kirk, Thank you for your inquiry. Most importantly first make sure the gas is fresh. Make sure all fuel lines are not blocked by removing them and blowing through them. Make sure fuel and air filters are not clogged. Make sure the spark plug is clean or new. Check for spark by removing the spark plug wire from the spark plug and inserting a screwdriver all the way into it to make contact with the connector at the top of the boot. Hold the handle of the spark plug and hold it close to the engine block and have someone else try and start it. Look for a spark to jump from the screwdriver to the engine block. If no spark you will have to check the magneto. To test a magneto you will need an OHM meter. Insert the red lead inside the spark plug boot, and touch it to the metal plate inside of the boot. Scratch the lead on the plate to ensure it is making good contact. Next, touch the meter's black lead to the metal coil housing and watch the meter. If the meter's display indicates a value of 2.5 to 5 K ohms, the coil is good. If the meter display shows a "1" or infinity sign, or the display needle jumps to the far right of the scale, then the coil is damaged and must be replaced. I hope this helps and good luck with your repair.

Hi Martin, Thank you for your question. If your snow blower starts then stops, you may have a clogged carburetor. If you have overfilled the engine with oil, it may seep into the carburetor and the carburetor will need to be cleaned. If fuel has been left in the snow blower for a long period of time, it can become thicker and heavier and clog the carburetor when it is in use. If the carburetor is clogged, it will need to be cleaned. If the carburetor is fine, check the fuel cap to see if the vent is clogged. If air cannot get into the vent on the fuel cap, a vapor lock will occur. This will cause the engine to stop. If the vent is clogged the fuel cap will need to be replaced. Check the spark plug to see if it is damaged or worn and test it to see if it is working. If it is not working, replace it. We hope this helps with the repair!
