|Cussboy||You did right in ditching the stock carburetor, more complex than the space shuttle. I've run a Weber 32/36 DGEV on my 1988 B2200 since 2005. My idle jets are 52 primary and 45 secondary.|

Horrible Fuel Economy....Carburetor? (1986 B2000 SE5)
When I bought this truck years ago, I was getting amazing fuel economy. Doing the math, I was getting up to 28mpg on the highway at times which is 4 more than advertised. This magic is no more.
After digging around and posting in several forums a couple years ago, I narrowed in on the carburetor. Having little expertise in carburetors, I decided to just install a Weber because it was cheaper than paying someone to even look at it (if in fact I could find a mechanic who can reliably work on a carburetor). Installing the Weber was easy and I managed to get it to idle well. Then I began to notice no power at all and continued awful fuel economy. Figured out the choke wire was bad and replaced it. This restored most of the power issues, but the MPG is still awful!
Does anyone have any suggestions as to why my 1992 full size diesel is getting better economy than my B2000? I have heard some talk of jet sizes, but I don't really know. I'm getting like 12-14 mpg...
Any help would be great. I have been keeping this truck going for a long time and it has taken me coast to coastmore than once.
