I never really liked the choke mechanism on the 34. It never seemed to work right. I used to take the bi-metallic coil off of the choke lever inside that housing and disconnect the hot wire. Then I tied the choke cam to the actuator arm so that the choke sits in a fully open position. Whenever I needed a choke I would depress the throttle arm and set the stop onto the choke cam and let it idle or warm up there. I'm not the kind of guy to jump into a car and let the car warm up as I drive so depending on what you do this might not be an easy thing to do. I always let the car warm up to being able to idle without choke before I set out. Again that's just me. The added bonus of all this, is that when you don't need the choke, it's not dumping a bunch of raw fuel down the intake for nothing. First thing, make sure that your parts aren't sticking, move the choke open and closed, make sure it moves freely. Second make sure you have adequate power supply to the choke. Take off the air cleaner, open the throttle wide to set the choke and then turn on the ignition and watch to see that the choke is unloading. There might even be a specific time lapse, check the Bentley manual. If you're set on using the choke, from what I remember you need to take the air cleaner off, loosen the three little screws on the choke housing and then while the engine is cold, pull the throttle wide open and see where the stepped cam lodges the choke open. It should be closed for the most part. If it's not, then turn that housing towards (counter clockwise) until it is. Don't go much beyond closed, the bi-metal spring will allow it to turn further but then it will take much longer for the choke to unload. I remember taking a few stabs at it and deciding the first way was just easier for me. I graduated to Kadrons too... I would never go back now. Good luck.
