I am also going to print that out for my wife's math classes. She teaches and is always on the lookout for answers to the dreaded
" when will I use this stuff?" THANKS

BTW I like 2 cyclers for ease of operation and care. an extra gallon of fuel each summer is OK with me.
Also the power to wieght ratio is better for 2 cycle. 4 cycle engines have done a lot of catching up in that dept. though.

I have to admit 4 cycle engines do sound cool, they aren't actually a lot quieter but the tone is more acceptable.
