I went the simple route for hand throttle
Hi Bob
Though all the my normal 216 engines and carbs have worked well with the hand throttle cable end just going through the hole on the throttle linkage see picture below. You will also note that the washer on the throttle linkage has been brazed to lock its position. This picture is of the side of the HUPs original 216 engine before the overhaul started.
But on the 261 Carb the cable is in just enough different position that it would stick requiring a very stiff return spring that was annoying to drive with, particularly as the throttle/gas peddle now actually is used to regulate speed instead of being an on or off switch.
Using the lever arm which is moved when the choke is out proved to be a simple way to set the idle speed up.
Cheers Phil
