'76 L20B stock fuel pump w/weber carb....

[1042medic]

My 76 KC L20B seems to always be begging for gas and sputtering ever since I put on this weber. Is my stock fuel pump sufficient for this carb or am I needing to upgrade it?

[TENDRIL]

how did you get the weber?  new /used /rebuilt?

 

possible float issue ? 

 

edit: stock F/pump should be just fine

I run a pure stock mechanical fuel pump with a Weber.  No regulator, return line connected.  I've had issues when the old (aftermarket plunger type) got weak.

Sorry guys back online, was gone a few weeks with the Army.

 

The weber was used when I put it on, it has sat through three deployments and seems to never work the same after I return from each. Thinking about just going back to the stock carb since I can't seem to adjust/work with this weber. I appreciate your help gentleman, just when I start making progress on my 76' KC I get another set of orders!! She's gonna be smiling soon!

have you disassembled it?

id disassemble and clean it. then check the min/max heights of the float.

from everything ive read, you dont connect the return line. i know mine isnt connected.

after you check the heights and reassmble it, you have to adjust the idle speed/idle, and fast idle

(3 different adjustment screws)

I'll do that, thank you Dawa.
