Alright I got the old carb off the engine in the Jimmy without too much trouble. Although I spent 30 minutes looking for a 1/2" wrench and couldn't find it, ended up just using a socket instead. I'm pretty sure there is 6 things I took off (labeled them) which went pretty smoothly. Here are some picstures: Carb off the manifold: side by side...old one is on left, "new" is on right: Why is this open on the old one: But closed on the "new" one: Whats this, and why does the new one have it, and the old one doesn't? Old: Why are these different on the side of the carb? Will the "new" one work on the Jimmy still? "New": Old: Please excuse the messy bench...thats why I'm not taking it apart yet, I have to clean it up. Do I need a stand for the carb? Or can I just set it on a block of wood like I do now to get the stuff off the bench? If I told you guys the numbers on the carb, would you beable to tell me what it means? Thanks...more pics later as I continue..tomrrow I will phone about a rebuild kit, and pick up some carb cleaner.
