Many, many, many years ago I purchased a new McCulloch 3216 chainsaw for my father. I liked it so much that I also bought one for me.
My father, who has since passed, was a terrific guy, but mechanics was not his forte. One day he told me his saw wouldn't start. I told him, no problem, we'll swap and I'll fix yours. When I got home I found the fuel tank filled w/ bar oil. Not wanting to disassemble it, I flushed fresh fuel into the tank and got it going by alternating spray start and WD-40 through the carb until all the crud was cleared and it resumed running great.
Fast forward to current time, the saw has not been working. The outward fault was the fuel primer bulb had cracked. A replacement w/ hoses and filters was ordered on eBay from China. Three weeks later the parts arrived.
When I disassembled the saw to change the bulb I also discovered all the fuel and oil lines had disintegrated. That was very handy because it made it impossible to document the original routing.
Through some research I found that the primer bulb pulls gasoline through the carburetor and dumps it back into the tank. The new primer bulb had no markings, so I used my pet food water bowl and fresh hoses to identify the in and out hose barbs.
The saw was disassembled and cleaned, including removing all the crumbled hose fragments from the fuel and the oil tanks. The kit was supplied w/ a fuel filter identical to the original. The original metal oil filter has a metal screen that was cleaned and the filter reused. The foam air filter disintegrated when washed, so I replaced it w/ an identical foam block that I already had on-hand, trimmed to the correct size.
The new fuel and oil hoses were poked into the small tank holes, after cutting the hose end at an angle, then pulled up to the fill hole to attach the filters. The hose ends were then returned to the interior, routed to the proper interior tank location, then to the correct exterior location.
The rest of the chainsaw was cleaned. It now looks very nice.
Now it starts right up and runs great again.
