Someone asked about the jets I am using in my Weber DGV 32/36.
The idle jets are changed from 55 to 45 and the main jets went 
down 1 size ( I can't remember the actual size).

To get at the idle jets, you unscrew the brass(?) screws on the 
side of the carb. If you are looking at the carb from the front 
of the car, they are on either side of the carb body, right next 
to the float chamber. When you remove the screw, the jet will come 
out with it, by removing the jet from its holder, you will see a 
number stamped on it.

The main jets are buried at the bottom of the float chamber. 
Remove the top of the carb body (the part to which the chokes are 
attached, and right at the bottom you wil see the main jets. Again 
they should have a number stamped on them.

I use a 12 ounce bottle of the 104+/MMO mixture for every tankfull of gas,
in my case that is about 7 gallons.  Why MMO ? I have no idea, as I stated
in my earlier posting, I experimented for a couple of months, and this I 
found to be the best combination. 

BTW my mileage went form 24 to 28/30 mpg, after I started using MMO, 
I don't know if it was related, but I surmise that the MMO, did a good 
job of cleaning out the gum/residue that may have accumulated in the carb.

Yes I have tried racing gas, and I always use this when I take my car 
to the track, however the nearest supplier is almost 10 miles away.
I find carrying 3 or 4 bottles of my concotion, is much handier, than
always having to drive to a gas station which cariies 100 ocatne fuel.
