This might help...
I'm not sure, but I believe the 34 has a Merriman pedestal. It probably doesn't matter though. In the Edson pedestal, and probably also in the Merriman, about halfway down the pedestal on the inside is a cable holder. It's function is to keep the cable housings in a rigid position so that the inner cable can slide and perform it's function. There is a bolt that goes through the pedestal to hold this in place. This is possibly what is causing your problem. It is a bit of a pain to get at but if this is the cause of your problem it must be either repaired or replaced. If you need a replacement and you do have the Merriman pedestal, which is almost impossible to find parts for, I would try calling Edson as they are usually very helpful.Good Luck, Len
