starting fluid, very detrimental?

No, no, no! Ya'll got it wrong! That stuff works great on my 2-stroke chainsaw after I noticed I didn't drain the old gas 3 years ago and she won't fire-up for some stupid reason...
:lol:

But seriously, I agree with using it in moderation. I've never witnessed any damage it has caused first-hand, but for over 50+ years I've heard the same things as what's already been posted, and since that dates back to Ancient Times (IOW, pre-internet), that's good enough for me.
