Emulsion Tube Removal

[sidecarKev]

How do I get them out? Carbs off a '79 F. I have the carbs all broke down except for those tubes. I want to make sure they are clear.

They should just press out toward the top of the carb. However, the tubes in mine were stuck very tightly.
I found a screw with the same threads as the jet that screws into the bottom of the tube. With the tube protected by using all of the threads possible, I tapped on the end of the screw to push the tube out.
I've used this procedure now on eight different tubes with no problems.

That did the trick. I thought they just pushed out but didn't want to force them too much until I knew for sure.

thanks

Reassembly

Make sure the notch on the tubes where the main jet screws into it aligns with the tab in the main jet bore when you put them back in. The square cut notch in the top of the tube that protrudes into the throttle body should face the engine side of the carb.

Good call! The emulsion tubes proved to be the main reason why my 78 didn't run properly. They were unbelievably filthy and no amount of soaking or spraying made any difference until I pulled and cleaned every little hole in them.

The tubes have been cleaned and reinserted. I'm glad I took them out. They had a real nice layer of crud covering most of the holes. Only thing left to do on this set of carbs is repair two of the floats. They were leaking.

Thanks for the help.
