Bought a gently used Centri from a friend. I used it for the first time today. It was great to come home and have some energy left! But my question is as I mentioned is the Centri adjustable somehow to make product "throw" further? I noticed the best I seem to get is 4 feet or so on each side. Is this right? Also noticed throttle cable sticks and comes loose too. I'm going to take the machine to my machine shop. I've got an idea that may fix the loosening up. I'll post pictures (If I can figure out how to do that!) when it is fixed.
