<p>The choke cable lever and fast idle cams aren't moving far
enough. Barely half of the cam is passing the fast idle screw
whereas virtually the whole of the arc should, and it's not moving
the jet lever down at all.</p>
<p>You probably need to move the inner down through its trunnion
clamp to get more movement of the lever. How far can you pull the
dash control? Mine is a good 1 3/8".</p>
<p>You may need to alter the position of the choke lever on the
shaft. When you have full travel pull it half-way and it should
make a right-angle with the line of the cable. If it's too low it
can make the start of the pull hard and if it's too high you may
not get enough travel.</p>
<p>See here <a class="moz-txt-link-freetext" href="https://www.mgb-stuff.org.uk/choke.htm#adjust2">https://www.mgb-stuff.org.uk/choke.htm#adjust2</a> for
pictures of the lever at zero and max choke, and of the fast idle
cam and jet lever with no choke, just at the start of enrichment,
and full enrichment.</p>
