CanTechZ Posted March 3, 2016 Share #13 Posted March 3, 2016 On 8/12/2014 at 7:51 AM, CanTechZ said: On my series I car the choke handle screw is an M2, the length under the head is 6mm and the head is 4mm diameter by 1.5mm high. It is a Phillips pan head type machine screw, if I have a small enough thread pitch gage I will check the pitch later today. On my 7'70 I recently noticed that the M2 screw for the choke knob that I was using was actually too long, the correct length should be 5mm. Using a 6mm long screw could cause damage to the knob if you over tighten. Here is a drawing showing the issue, and a couple of 3D model images: Link to comment https://www.classiczcars.com/topic/49799-that-little-screw-holding-the-choke-lever/?page=2#findComment-487737 Share on other sites More sharing options...
beerdart Posted March 3, 2016 Share #14 Posted March 3, 2016 Here are a few pics and models of the chokes and aux throttle. I have 3D printed a set for my 1970.

beerdart Posted March 4, 2016 Share #15 Posted March 4, 2016 A few more and the CAD files that a friend made up. https://grabcad.com/library/choke-and-throttle-handles-for-datsun-s30-1971-72-1 Link to comment https://www.classiczcars.com/topic/49799-that-little-screw-holding-the-choke-lever/?page=2#findComment-487785 Share on other sites More sharing options...
psdenno Posted March 4, 2016 Share #16 Posted March 4, 2016 (edited) The red handles would certainly liven up the interior if one wasn't concerned about orginality. I like it.

We're getting off topic as this thread started with a discussion of "that little screw". I will start a new thread for discussing 3d modeling of S30 parts. Anyway here a couple screen shots of the choke assembly so far: Link to comment https://www.classiczcars.com/topic/49799-that-little-screw-holding-the-choke-lever/?page=2#findComment-487801 Share on other sites More sharing options...
