Pierburg carb on a w124 200 Problem

[hkssport]

hi guys, please help me out on this. My engine for some weird reason idles on start only if i put a rag on top of the carb to restrict air intake. once i take it out, the engine dies. I have replace the gasket already and have done the leak test but still failed. This is already one month of headache for me. The chamber where the float is situated gets filled but it doesn't dispense the fuel into the engine. Please give me your precious suggestions, thanks in advance

Hello and welcome to the forum.


Is a jet blocked or is it the thermo cold start not working, if the car is fine when warm, then the cold start only

sir television, i have let it run with that rag on top for about 30 mins so the engine would heat up, it still didn't work. when i took off the rag, kapoot! dead again.

 

[hkssport]

sir roofless where do i find that diaphragm?

 

[television]

Then a blocked jet I think,,take them out and blow through them, do not damage the thin gasket

 

[hkssport]

ok sir i'll do that. after that, what could i check next cuz i have assembled and disassembled the carb about 10 times looking for leaks and blockages. thank you again. i hope you wont get tired of helping me out.

when you open the throttle is the fuel squirting down the carb

A conversion might be the best thing and use a Weber, as they fit OK

wow, i should follow this tomorrow morning when i wake for i am at the other side of the world, the philippines. thanks sir and i will surely give you a feedback after i exhaust all of these instructions you gave me. thank you so much again.

 

[hkssport]

sir roofless, i thought of that also because it might be a mechanical fuel pump failure but i temporarily installed an electric fuel pump just to see if it will add more pressure to squirt out the gasoline. the answer is yes it squirts out gas when it is starved from air by a rag and no it doesn't squirt out gas when started normally.

replacement parts availability is bad here sir television, i sense that you have parts for this. is it possible to buy from you just in case everything fails? but just a thought from me to get me going....if its made by man , it can be fixed by man hehehehe

I think that in order to provide suitable information, we need to be sure if we are dealing with a 2E2, a 2E3, or a 2EE - they are really quite different devices, with different common failures.

For example, if it is a 2EE, it's entirely possible that the fault is electrical / electronic and nothing at all to do with the carb itself.

Is this problem only when the engine is cold,or does it persist even when the engine is warm?
