Here’s how to remove the air correction jets, fuel emulsion tubes and fuel jets from a Weber 32/36 DGV, DGEV, DGAV, DFV, DFEV, DFAV carburetor. First off, the air correction jets. They are located here:
A well-fitting flathead screwdriver removes these – make sure it fits well as the brass is quite soft:
They will probably be different sizes in either location so make note of which came from where. If you need replacements or alternate sizes check out eBay US or eBay AU. Here we have 145 in one spot and 175 in the other – the size is stamped into the top of the jet, though it may well be very hard to make out if they are dirty. If you can’t make out either number simply make a note of which came from which location so you can put them back where they came from.
Beneath the air correction jets are the emulsion tubes, where the air and fuel is mixed.
If turning the carb upside down and tapping it doesn’t cause them to fall out (don’t lose them) you can gently remove them by inserting a straight pick or scribe tool, angling it very slightly to apply light sidewards pressure and lifting. Remember that the emulsion tubes are brass and very easily damaged if you are going to do this. Alternately, if you have an ultrasonic cleaner stick the carbs upside down into the cleaner for the first run and they should fall out.
They will have an ID on them – these are F66:
If you need more emulsion tubes you might find some on eBay US or eBay AU. With both of those removed, look at the fuel jets inside the float bowl:
Again, a well fitting flathead screwdriver will be necessary to get them out. The same as the air correction jets, they will probably be different in each location so take note of which came from where.
The size is stamped into the side – on this carb 132 and 127:
That’s it for these steps – now go back to the main 32/36 page for the next.
