Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I tried to find it but could====it was a discussion about oiling the foam precleaner.    Brigg,s recommends oiling---Tecumseh does not.   What are your thoughts of this?  Who is right---Brigg,s or Tecumseh?   I want to believe Tecumseh-- for oiling makes for a mess and I am not too much on washing in soap and water and reusing.  I usually replace.   On my TVT-691 Tecumseh I merely blow it out  from the engine side and reuse it usually for a season and then replace>(sometimes both filters) Appreciate your thoughts on this subject.----Your friend Will
