In an effort to fix my DEK 15 HP chipper, I need to buy a single pulley centrifugal clutch as they are the distributors of the brand. My DIY repair of the clutch failed, but I had fun making sparks and cutting stuff up. I've emailed GXI with questions - no answer. I've called their listed phone number, and tried every automated menu choice to try to speak to someone, with no success. Their website states all sales are final, and I'm having a difficult time thinking it would be a successful transaction. The only clutch I could find that would fit the specs on the machine was $384 and a 10-day shipping window. I'm not sure the machine is worth that, even though it's been run only 20 hours. Any advice/experiences with GXI would be great. Thanks!
