Good To Know

Q: Do I need to break in the new piston? A: Yes, after installation run the saw at varying throttle for the first few tanks of fuel with a slightly richer oil mix, then return to a normal 50:1 ratio.

Q: Will this fit all MS271 and MS291 chainsaws? A: This 47mm kit fits all MS271, MS271C, and MS291 chainsaws that use a 47mm bore; verify your model’s bore specification before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
