I'm rebuilding my CH601. After reviewing over 1000 photos of my original build I cannot find one picture of my throttle and choke attachment to the carb. I have a 3300 with Bing carby. Does anyone have a photo of their 3300 setup at the carb? I can't recall whether I used the extension piece on the throttle assembly at the carby or not. Also, I hear that folks are using the larger gauge oil lines from filter to cooler. If anyone has that spec please let me know I'd like to do the same. Slowly, but surely, she's coming together.

Here's a picture that I think is from one of Jabiru's manuals:

It is very similar to how I have the Jab 3300 on my CH750 hooked up. One thing I did was drill a hole in the throttle arm extension just below where the cable is attached. I found that using the original hole gave an "over-center" resistance - in other words, as the throttle arm extension was pushed forward, it would flex the cable upwards, causing resistance. Then, once past center throttle, it would flex back down to normal position. By moving the hole down a little and bending the end of the throttle cable up a few degrees, I got a much more smooth operation of the throttle and there was still plenty of throttle travel.

One other thing not shown in the picture is I put a few wraps of safety wire around the cables and wired them to the bracket that holds them for "just in case" security!

Hope this helps,



Thanks for the reply. The Jabiru Manual sent did not have this photo. I'm going to check to see whether there is a Zenith-specific install manual. Seems the one I have is for the Jabiru airplane.
