Small Engines (Lawn Mowers, etc.): McCulloch Brush Cutter

Question
QUESTION: Many years ago, I purchased a McCuloch Brush Cutter brand new.  Over the years I have lost the documentation that came with the machine.  I recently had the throttle cable break at the trigger.  It appears as though I have to take the case apart to replace it.  Can you give me instructions so that I don't dismantle anything that isn't necessary?  I would also appreciate the part number of the cable.  My machine is a MAC3227 straight shaft J pole.  The numbers I found on a white tag are as follows:
CT  M  32CC  SMH3-032UB24RA  EM
CO92

Under the logo, I found also 46767-38  .    Can you tell me when this was manufactured?

ANSWER: I believe it was manufactured in the mid 90's.  

You can still purchase throttle cables for the machine.

To replace the throttle cable I just remove it from the trigger, remove the shaft from the machine, remove the old cable and install the new one.   It is pretty straight forward on that machine.

QUESTION: Thanks for responding.  I managed to get it done, but with some difficulty.  Everything has to be positioned just right to get things back together.  I didn't realize the kill switch wires and throttle has to be on the outside of the little plactic tube inside the shaft housing.  Also, I see I had a typo in my original question.  The numbers should have read CT  M  32CC  SMH032UB24RA   EM instead of what I sent originally.  I am beginning to wonder if I should just get me a new one as when I pulled the rope starter, the rope will not now retract.  Thanks again for responding.  I don't really have a question unless you want to tell me how to access the rope pull.

Answer
To access the rope pull you have to dis-assemble the unit again.

Before you completely strip off all the parts, each time you remove a major part, such as the shaft or a housing, test to see if the rope starts working again.  I have seen some parts bind preventing the rope from working.
