Recommended Posts

how many times can you rebuild a weber 32/36 dgev? Ive rebuilt mine once before.ihave had it for 20 years.Should i just buy a new one? i plan on keeping the truck.I have replaced the throttle shaft bushings with bearing kit.i have noticed a little difference in the performance over the years.I know nothing last forever.Just wondering if itss time to just get a new one.

If the DGV is not stamped with "5A", it means it is a really old carb. Weber made some design changes starting with the 5A that make it run better during the transition from primary to secondary.

It has made in Spain stamped on the carb just below the fuel inlet on the left side.

Stamped or cast?

 

Did you look for the 5A on the base?

it is cast i will look tomorrow for the 5a I bought this from 20 years ago from performance parts in New york.On the dgev the emulsion tubes have stamps on them.My father was disassembling the carb .He turned it upside and the tubes fell out one has f66 stamped on it.not sure what the other one has because i cannot read the stamping.is there anywhere i can get a repair or rebuild manual detailing these locations ?Just trying to get my 720 rolling again.i looked and DGAV S32 is stamped in the carb base.I also noticed that the primary jet and secondary jet were both stamped 135?

You can use this as a guide.  Lots of info.  There are also youtubes that people rebuild for reference, but be mindful that they are as good as the people making them.  "Grain of salt, if you will."
