So something interesting happened today. First time I've seen this in person. Its 90 today and humid as a fat chicks underboob. After mowing all our biking trails I grab up one of my little Remington Mighty Might saws to tune up some low hanging brush on said trails. Near the end of the tank its running all erratic and tuning does nothing and it dies. Cools off a bit and fires back up. Runs a bit, starts the same *s-worde. I pop the fuel cap and what was left blew all over. This is the older all magnesium version of the saw, tank and all, and its so hot I can't touch it. I drive a 1/4 mile back to the garage with ma lil rider, fill up the saw and the fuel boils for several minutes in the shade with the cap off. I was almost afraid to use it. Now I know why they lengthened the Mighty Might saws in the front and changed to a plastic tank inside the magnesium case. At least that's my thinking anyway. I need to run the plastic tank unit I have here to see. Supposed to be as hot tomorrow and Friday.
