Sorry, we couldn't find any existing installation instruction that matched.

My wife ran over my Tanana edger with my pickup, smashing one wheel, and breaking the carburetor off, along with other parts.

At first I thought it was totaled, but I like to tinker, the edger is 50 years old. I pounded on the wheel to try to get it round again, and found a axle bolt to replace the bent one, it looks pretty bad but it does roll, then I started to remove the hoses and linkage to the carb. The carb actually looked ok, but a part called a carbureto r insulator, was broken and the screws that held it to the engine were bent, I had previously pulled the rope to see if it had compression which it did so assumed the engine had no cracks in it. The only part that I could visibly see broken was the carburetor insulator. So I set out to look for parts, because of it\'s age I thought it would be impossible to find, but to my surprise several parts houses listed and showed parts to replace what I needed, The parts were more than I wanted to pay but I did so anyway. They even had the exact duplicate wheel, which I may replace at a later date, it took awhile to get because the parts had to come from the manufacturer about 30 days, I checked at first to make sure they were right, and they were, so then I started to put it back together, those small carbs and linkages are a pain to work on but I did it, and it appeared to be right, connected up the air hoses, and pulled the rope, I didn\'t give it much hope, but with a squirt of ether, it came to life, and never ran so good before. I was extremely happy. It was worth my time and expense and I thank replacement parts for finding the parts I needed. One reason it still runs is because I never used ethanol fuel, that stuff is so terrible on aluminum and carb parts that if you use it you need a need a new carb every season, never use ethanol fuel in small engines it\'s death to them.
