I have been in charge of my moms snowblowers ever since she got divorced. This means im the guy winterizing and summarizing them. Few years ago in the fall I replaced the plug, mixed up some fresh gas and oil and got it ready for her. Saw this Dupont snow blower spray at the store and said can't hurt right? Well ever since I sprayed that shit the blower seems to clog up very easy. Few inches of light snow cogs, heavy wet snow, forget about using it at all. Anyway to make it work like it used to or is it junk? I cannot imagine it just started running like shit on coincidence right after I sprayed this stuff.
