The odd fittings you need to go from the C-section to the wings aren't available from ACS or Wicks, the place I found them was Murdoch Industrial. I realize there are differences between the 650 and the HDS, but my main point is, the odd fittings you'll need are available from Murdoch.

Does anyone have such a set up and has it caused any problems as opposed to the standard push throttle? I realize a person can get used to anything, but this seems counter intuitive. Yes, No? Terry Turnquist 601XL ________________________________ Message 5 _____________________________________ Time: 07:39:26 PM PST US From: Bryan Martin Subject: Re: Zenith601-List: throttle set-up The throttles should be push to open. The Bing carbs are spring loaded to open throttle and you have to pull against the springs to close the throttles. You should try to keep all the major systems as standard as practical. There's no good reason not to set the throttles up for push to open. On Sep 19, 2009, at 8:54 PM, Terry Turnquist wrote: > It looks like the dual throttle set up shown on 6-E-5 is a "pull " > system.

I would also eliminate the spring action that provides no safety or intuitive motion or resolution if one spring breaks. It's not as hard to do a type certified example if you really set your mind to it. When ever would you allow someone to fly your aircraft if it were different from the expected thing. That becomes a safety issue, big time. Yes, counter intuitive is incorrect!

The thickness of the inner throttle cable and the arc through which it is required to operate make opening (and closing) the throttle difficult.
