Ok, so I'm in the process of a thorough restoration of a duplex carb off a 60. I will be putting it back on the tractor this week/weekend and I've been researching the adjustment of it. I watched the Steiner video on youtube and I've read manuals and online how to do it. From what I gather this is how it's done.
1. With the governor-to-carb linkage attached, adjust the hand lever-to-governor spring linkage until 600 rpm is reached (with the hand lever all the way back)
2. Adjust the governor arm stop screw until there is a 1/8" gap between the throttle shaft stop screw (on the carb) and the stop peg.
3. With the governor-to-carb linkage disconnected hold throttle shaft against stop and adjust stop screw until 300 rpm is reached.
4. Short out each cylinder one at a time while adjusting the opposite idle screw. Find the faster cylinder and match it to the slower one. Here is where my confusion is. Do I do the idle adjustments with the governor linkage hooked up or do I disconnect it and use a rubber band or zip tie to hold the throttle shaft against the stop screw?
Should I wait to do step 3 until after I adjust the idle screws correctly?
