My name is Eoin (Ian), and although I am not "New" to chainsaws, I have developed a renewed interest in how they work and how to keep them working well. Most of my Google searches have eventually led to the Arboristsite forums.
I purchased a McCulloch PM425AV18 in 1998. Over the years, I've rebuilt the carb, changed to Oregon bar and VersaCut chain. It continues to serve me well. That model was sold at Canadian Tire stores. My searches have suggested that it "might" also be referred to as MS1838av or Mac Cat 839 in different locales .
In 2020, a coworker , who was moving into an apartment, gifted me his Troy-Bilt TB3516cc. It appears to be the same as /similar to a McCulloch MCC1635AV. It had a 16 inch bar with a very dull chain. It barely ran when I got it. At that time I didn't have a compression gauge , but the ease with which the starter rope could be pulled, suggested that compression was low. When I pulled the muffler, the portions of the cylinder/piston visible were not scored but rings were not moving. I filled the chamber with Red Armor, and left it sit for 3 days. After draining the oil, the compression "felt" better . After initial smoking on startup , it settled down to a steady , but elevated idle (which I promptly adjusted down to stop chain moving). Since then , I have gone to a 14 inch Oregon bar with a VersaCut chain.
I have recently purchased a compression gauge , inductive tachometer/hour , long Torx bit for my driver.
Great Site, glad to be here.
Thanks
Eoin
