No, I won't be putting one of the Chinese carbs on it. The previous owner, who admitted not being mechanically inclined, put a new carb on it and threw away the original (ugh) because it was completely gummed up from sitting. The carb he put on it is from ebay and isn't correct. It looks like possibly a trx250ex carb (no vacuum lines or diaphram) but it's jetted 78/32. It does say 'Japan' on it, but the only number on it doesn't cross-reference to anything.
