Hey all,

 

I'm in the process of rebuilding my weber and upon taking off the power valve diaphragm I noticed that on one of the three raised "prongs" in the diaphragm housing on the carb (not the PVD itself), has a noticeable burr, peak, raised metal point, whatever you want to call it, and it has left a small mark/dent in the diaphragm itself. It almost looks like someone tack welded that little raised bump in there, but obviously thats not the case.

 

Nevertheless, I need a new diaphragm but I want to know if I can/should file down that burr, and most important, what could have caused that to happen...

 

Any suggestions?

 

PICS

I, would remove it.

well yes, obviously. I was more concerned with what could have caused something like this to occur in the first place. If it's something that needs to be repaired, I'd like to do it now while I have everything apart.

 

Thanks

Probally no definet answer to it. Lot of "could be's".

 

Casting defect from impurities in the aluminum that got thru inspection,

someone may have had carb apart in the past and some debri got in there un-noticed by assembler,

numerous possible other causes.
