Customer Reviews
Overall, I am fairly pleased with this product.
The kit includes almost all the necessary components for a complete cylinder and piston replacement, and everything seems to be of decent quality. The cylinder itself is made of durable materials and has a good finish, while the piston appears to be well-made and fits snugly inside the cylinder.
The installation process was relatively straightforward and I was able to get everything installed and running in a reasonable amount of time. Once installed, the chainsaw ran smoothly and seemed to have improved performance compared to before the replacement.
Fast shipping,great value.
Great deal and good shipping. I will use them again.
installing was easy everything bolts right together only have couple rides on it still in break in process but after the first initial start and brake in I've been running it fairly hard and just keeps amazing me definitely would recommend and don't have rejet the card runs perfectly on stock carb with no adjustment done
Good parts, they fit just as well as the 1979 oem parts.
