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


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

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.

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.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
