I've got an 87 2600 that had the weber on it, and it drove like crap (low power, 12-15mpg) even after a carb rebuild. I got the original carb on ebay for $50, but holy crap there's alot of vacuum lilnes - the diagram on the hood and the Haynes manual are no help -anybody have a oicture of their carb or any idea where I could find a better diagram? Thanks - Greg

 

what you need to do is go to the weber website and request a tuning manual for that specific carb. I promise you if tuned correctly you will get substantial more power and better gas mileage than with the stocker. I have a .380 weber and get great power and fuel effeciency.

 

Did that - got the rebuild kit, etc - it went up from 12 to 15, maybe 16 or so on the highway. But from what I hear, the original carbs were crap, so I'm going to switch it back the the weber and live with it while I finish my diesel rabbit and get 50 mpg while going just as fast....

 

What kind of Weber do you have on it? If you have the 38, that's ALOT of carb for a stock engine. You'll run VERY rich and be doggy on top of fouling out plugs. The 32/36 carb would be best for MOST engines. Let me know what you have and we can go from there.
BTW, with my Weber 38 and stock tires I get about 16-18mpg and with my 35's on it's between 12-14mpg (and that's with ALOT of tire).

 

when you give up ill giv you fifty bucks and my carb for your webber
