alright mike, does this one run carts without having to wrap rubber bands around the machine? can you just put on the grip and cart and go? with the one rubber band of course, I run only carts, have always been interested in your machine, but if I cant just run carts without having to wrap rubber bands around it, it kind of turns me off a bit. thanks for any info you can give me. also what is the maintenance required for this one to run? lubing every so often, or what ?
