First of all, the carb model number is on the pass. side corner facing forward and near the bolt hole. It will be 14XX in .25 numbers.

These carbs are very sensitive to dirt and almost running the car out of gas, may have sucked some through. They just wont idle, but will run kinda OK at higher throttle.

Super simple to clean out - assuming you have the Torx drivers. Two screws to pull the metering rod covers and then the metering rods out, eight to pull the top cover and 2-3 tiny spring clips for the linkage. You are now inside then manually clean out the bowls. With the top cover in hand, pull the floats, then the needle and seats(keep these parts matched as to where they came from or face resetting float level and drop) - there is a screen on the casting side of the seat that gets cruddy, clean it off.

Unless you have at least a gasket kit, do NOT pull the 10 screws inside the carb as the gaskets often stick and get torn apart - regardless, you don't want to do that with the carb on the engine.

These are fun/simple carbs to work on - I just fully rebuilt two of mine this past week.

One is ready to be reassembled, the other you can just see at the top of the photo

Egr ?

If you still have the EGR, how is it a slight coincidence it started leaking at the same time.
