Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you. Did you notice the white exhaust prior to added more gas to your fuel tank?
Thanks for your reply. What is the brand of your engine, and the size?
Thanks for this information. Check your oil level. Also, check to see if your oil smell like gas is mixed in with it. Have you tilted your mower for any reason recently?
Thanks for confirming. Have you tilted your snow thrower recently? Thanks for the engine information also.
If your oil level is fine, and it does not smell like gas, the white smoke should clear after a few minutes of running your engine.
