So I have a old jiffy 77 that has been awesome for the last 12 years and today it won't idle without choke. So I grab my back up auger a Eskimo with a viper motor that has sat for a year.....and the tank has a crack in it! I never use it....is this common? Next question my jiffy calls for 24:1, has anybody run that 40:1 fuel from Canadian tire?
