I have the answer from Edson already! Good Morning John, Thank you for your inquiry. You can drill and tap for a screw. The size we use is 1/4-20 x 1/2". The bushing is the same. Another suggestion would be to install a rope/bulldog clamp on to the throttle cable down near the throttle lever on the engine. Gently tighten the clamp thus applying friction to the outside of the cable. Over tightening the clamp will damage the cable. I'm sorry I do not have a detailed drawing I can send you. I hope this helps. Please feel free to e-mail me with questions. Sincerely, Ken Martin Customer Service
My comments about the "rope/bulldog clamp" suggestion, just don't do it! The throttle control lever pulls tension to increase RPM, the engine throttle return spring returns the throttle back to idle. If the clamp is tight enough to keep the spring from pulling back, then you may not be able to decrease RPM, which in turn could put a hole into your bow ;-) John C27TR #5956 Austin, TX John Oppenheimer wrote: > Yes, getting the four screws out was difficult.
