I purchased this in September and put an OEM Husqvarna closed port 365 cylinder with a Tacomic piston on it. It's had aprox 5 tanks ran through it. The bar and chain are not included. I'll include the open port cylinder and piston if you want it.
Everything is Chinese except the cylinder and the piston. I got it off Aliexpress and took the open port cylinder off and put a closed port oem 365 cylinder I had on it.
