This was on my 37 pu.Just some Heim joints and steel rods ,Cheap, easy and it works smoothly. I removed the round covers on the auto chokes, silver soldiered linkage arms onto the existing little arms . Linked the two together with a length of rod with the choke hooked up on rear carb.You can just pump the gas a few times, no choke, the engine starts right up, then just feather the gas pedal for the first few minutes.
