If you can get some Seafoam there, add some of that to the gas to get rid of all of the crud in the carb and engine. It will clean it out for you real good. I use it religiously in both of my motors (6 HP & 70HP). You can use a full 16 oz. can of it to 6 gallons of fuel the first use to clean things out, then 1 oz. per gallon after that.
NOTE: Thank you, & you have a great Christmas as well!!
