I use it liberally on my old motors for the first start of the season, the 25 year old lawnboy and the really old B&S rototiller. No issues so far but those motors are a bit worn anyways. I won't use it on my 372xp, but it starts pretty easily.I use starting fluid on gas engines all the time... weed wacker, push lawnmower, chain saw. If they sit around and won't start after a half dozen or so pulls a little squirt of starting fluid gets them going. Never experienced any knocking, explosions, etc. Maybe I'm just lucky.
I use to use it on my old snowmobile too, with no bad experiences. I'm sure it wasn't great for the motors but if I got 50 hours of running a year in, I was lucky.
