RE: weed eater engine
I was originally going to use one for my project, however, I found that cc's do not translate to hp or torque the way I thought. Most engines like homelites, only have 1-1.5hp, and not much torque at all. Look at it this way, you hit some small area of thick grass and you can stall it out at full throttle. Also, the major disadvantage, is finding one with a clutch adds money, and it still again doesn't work well with a drive system.
