Jim,
Thanks for the compliment. As for your question, yes, I build all my engines. My engine of choice is West Bends 580/700's but I have built a couple Homelite K92's and Clinton E65's. Most of these engines have included the use of your Max-Torque clutches. If you're interested in seeing some of my other engines, karts or mini bike please feel free to email me
