First off let me say it is not to push my fat a$$ around. I got a another gas powerd weedeater from the nieghbor but I dont need tow and I have a industral one I bought last year (the kind with the handel bars) and I thought I would use the engine of the indsutrail one to make a small go-cart for my kids. I figure it would have to push about 250#s max and thats figuring about 100-150#'s for the cart itself. So do you guys think this would be ok or would it just be a good way to destroy a good weedeater? P.S. This thing doesnt have to have go at brake neck speed my oldest kid is almost 4.
