Re: R51/3-carbs leakage and tuning issues

Thanks Tommy.
Will try this also.

How can I remove the floats needle? I think it is soldered there in some way.

Re: R51/3-carbs leakage and tuning issues

Thanks George, I appreciate your time and efforts. My problem is the leaking of this idle adjustment screw, understanding that it is not the problem itself. I need to find out why it is leaking, and heavily while bike is on its center stand. I swapped floats with no change. It is always the left car...

Re: R51/3-carbs leakage and tuning issues

I also do not think the cause of the leak is this screw, I assume it is leaking there because of another problem, from the little I understand in the carburetor field.

Re: R51/3-carbs leakage and tuning issues

Well I never touched that and took the float out carefully and put it aside while cleaning took place. I am tempted to take that leaking fuel bolt out and take a look inside (the whole cleaning/soaking process took place with this leaking mix screw in place). What do you guys think? I admit I was af...

Re: R51/3-carbs leakage and tuning issues

James,
If you mean that rod or needle that is going through the float: I never touched it and am not sure one can take it appart, but maybe I am wrong here.
Anyway, there are no grooves on that one.

Re: R51/3-carbs leakage and tuning issues

Try swapping the floats Check the 2 floats and see that they both have a small washer on top of the float #40 in salis pic If one is missing the float has to rise too high which will flood that side https://www.bmwclassicmotorcycles.com/parts/all-parts/carburetor/ Tommy Yes the washers are there. S...

Re: R51/3-carbs leakage and tuning issues

Hi James and all you friends here,
Yes, the valve in that cover is sealing well and stops the air flow from my mouth.
I am not sure what do you mean by "where the float is riding on the shaft". Can you please explain?
Thanks!

Re: A small hole in the carburetor

That's the thing, it's a little hard for me to know when the hole occurred. It was there before the vinegar soaking, I'm sure of that. It should not be forgotten that the bike stood for several years with a fuel system that was not drained or cleaned. Anyway, I finally decided to try with an engine ...

Re: A small hole in the carburetor

This tiny hole burst into the hole through which I inserted the wire. The wire can be seen through it. After more research and studying online into the night ;) , I already realized unfortunately that it should not be there. I intend to use https://www.quiksteel.com/, as it is a material that can be...
