A: 4300 is basic (earlier version) and 4350 has a high altitude compensator. From: "Ralph Bade" <rbade@xxxxxxxxxxxxxxxxx> To: mail@xxxxxxxxxxxx Subject: RE: I need Carburetor Help for rebuild??? Date: Thu, 24 Feb 2005 20:47:53 -0600 Message-ID: <LPBBKPNJCNGELBJINCAECEICDLAA.rbade@xxxxxxxxxxxxxxxxx> Thank you Randy! Now I just have to determine whether its a 4300 or 4350. I'm clueless about the choke part number and I'm guessing here, but I'm thinking the carb is from a 1974 model based on the first digit of those numbers. Thank you for the info on the intake. I learned something new today.
