Señor Brat Posted May 18, 2012 Share Posted May 18, 2012 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?

Señor Brat Posted May 21, 2012 Author Share Posted May 21, 2012 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 Link to comment Share on other sites More sharing options...
TomRhere Posted May 21, 2012 Share Posted May 21, 2012 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.
