I've got an Edelbrock #1406 (600CFM, electric choke) that I was told didn't function that I'm trying to get running to put on a pile that I bought. After tearing it apart and cleaning most of it I don't see anything wrong other than the only thing dirtier inside is a bucket of sand. I'm a Quadrabog guy. There are some things that bother me: 1. I only found one pair of metering rods (primaries). Am I missing something? 2. The secondary air valve is non-adjustable. Do you grind on the weights to make it open faster? 3. There is some kind of square brass and stainless ball thing at the front middle of the carb. I'm not sure if these were put in right. Looks like some kind of loony vent system. Makes sense that the stainless ball goes on the bottom and the square piece of brass on top. Any ideas? 4. It looks like gravity and fuel pressure with the help of magic makes the needle move with the floats. Are there supposed to be springs holding the needle to the float? 5. It appears that there are linkages missing on the outside of the carb. I've got coathangers if you've got pictures? and lastly, 6. What kind of goon would use one of these carbs on an offroad vehicle? It looks like it'd function worse than having a baboon sitting under the hood squirting gas down the throttle body when you pulled on its tail.
