For Novarossi experts
Looking to rebuild a 421B as a back up engine but I damaged the cylinder and piston. Was working great before that. I know there are some new cylinder and piston combo's out there for the 421B but they are crazy expensive. I think it may be due to parts being harder to fine. I was wondering what other piston/sleeve from another novarossi engine or even other brand engine I could use. Again looking to use it as a back up engine.
Thanks!
