As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Broken carb internals

Hello,

Going through the carbs on my newly acquired '82 650e.

Here's the problem: PO broke one of the two "pillars" that holds the float pin in place. It looks like he used some sort of epoxy or jb weld or something to hold it together, but it promptly came apart after poking around.

My question: how f'd am i? can i use jb weld or the like to re-attach the piece? will this hold up to gasoline? do i need a new carb body??

Thanks
 
JB Weld won't hold up with petrol in there. You need to either solder the pillar back or fix it by pinning. Loads of threads on here where guys have done that - have a hunt using search and you'll find some pretty detailed accounts.

Or, get hold of another carb of course.
 
Yes there are threads on how to do it. I have used the roll pin approach with much success , just be very careful centering you drill and how deep you drill into the carb body. good luck :)
 
I bought this product to repair broken posts,

http://www.por15.com/PORPATCH/productinfo/PPB/

but carbs are on the bench and have not been used to determine whether the product will work and won't be installed any time soon. I had planned to test the product separate from the carbs but never got a round to it.

If this product fails I will drill and pin.
 
excellent, thanks for the responses and kindness towards the uninitiated.

i am interested in /u/ crazy5's method of drilling and then using a 12g wire as the the pin.
and/or soldering the post in place. either as a standalone or in conjunction with the drill and pin.
followups: will solder adhere to the carb body? will it hold up to petrol? if so which type of solder?

thanks again and sorry for any redundancies!
