Re: [ihc] anti-backfire valve

-John,

---The only reason I call them a flame arrestor is because that is what they
are called and I need to remember as much of the real* names as I can before
I get into the stages of my life that I will start forgetting things. I
intend on having IHs for life, whichever comes first, my demise or the last
IH in my driveway. I just hope they intend on burying me and not letting me
rot in the driveway like the last IH will. <G>

---While we are also on the topic of parts, would you happen to have just
the frames for slider windows? There was a set on eBay and UPS wanted $70 a
pair to ship, so I opted out of the bidding. The real pincher was, the
windows were in the Chicago area... where I used to live, and the only parts
I have found here in Alabama, are the ones that I left Michigan with. I feel
like I am hording parts, so I intend on going through the storage building
and listing parts here, then three or four weeks later, listing them on the
BB and then a couple of weeks later, listing them on eBay... by then I will
understand how much moolah eBay wants for my using their services.

---Thank you,
