Motorcycle chain lube makes the chain run quietly on my blower. The only noise I hear is the second stage rotor scraping slightly. It has been that way for years so it must be OK.
It is possible that it's my second stage rotor. It's not screeching or anything. I purchased chainsaw gear lube for the chain. Will test some more. Lots of rotating parts, and I am sure it's not supposed to be silent or anything. I can rotate everything smoothly by hand. I have to check to make sure that the chain has 1/4 in deflection, as stated in the manual.Motorcycle chain lube makes the chain run quietly on my blower.
