I went to the Borg to get a new chain for my 16" chain saw.
The generic brand they sell had 4 - 5 different 16" chains with the number of teeth ranging from something like 56 to 60.
Each version showed the same list of manufacturers (Echo, Homelite, Stihl, etc) but each version had a different list of model numbers under each manufacturer's name.
For example, only the 56 tooth model had my chain saw's model number on the package but all versions had my brand listed.
So what would happen if I put, let's say, a 60 tooth chain that matches my brand of chain saw but not my model?
In other words, what's the difference between two 16" chain saws for the same brand of saw, one that uses a 57 tooth chain and one that uses a 58 (or 59 or 60) tooth chain?
