I took the carb bowl gasket out of my 250sx and put it in a Kawasaki enduro carb I was fixing for someone. The shape was a little different but it fit. I ordered a 250sx carb kit off of eBay and the bowl gasket is slightly too large. The shape is also a bit different but more importantly it’s just too long. I even tried freezing it to try and shrink it. I bought a rebuilt 250sx carb from someone on this site a couple years ago. I had sent them my original and after bench testing they said it was just too worn out to be calibrated so they sent me a fully refurbished unit and I’m not sure what year it is. I’m trying to attach a pic from my iPhone but it’s not working
