I'm not sure who to address this to as you don't seem to have an engine department anymore. I hope someone can help me find a needle valve for my Irvine .40 engine. I broke the needle in a crash and want to use the engine again. This engine is the best! Brute power, smooth throttle response, one flip starting. I got it at a swap meet many years ago and the previous owner had altered the screws that retain the carburetor so I can't just replace that whole unit. Any suggestions? I'm not good at computers so don't suggest the internet.
