well, all the engines are on my own equipment, except for the edger. i usually repair them with help from my dad, but i have been repairing the edger my self. some people think its weird that i do it myself, because i'm only 14!
the engine sort of speeds up, then the RPMs go down like it is trying to "die", when it is running at an idle. also, the engine was made in 1969, and it still has the origional crankshaft, rod, piston, and carb.
