A close look at the pump circuit on the DCOE & DCO Weber carburettor., and how the different parts can be used to tune the Pump process.

Thank you. I have a huge flat spot where it leans out off the line so I'll get a fatter spring in there and make sure I have max throw and flow.

Hey
You do some fantastic videos!
I enjoyed them very much.
Any chance of you doing one with bearings?
I got mine hydro-blasted, and I don't want to take a chance with them getting rust and stick/getting stock open.
Thanks in advance.

Hi is this pump circuit same on the dcoe 40 138 139 emissions carbs

Can the rod be trimmed at all. My dcoe40 seems like it hits to early.
It’s spurts on the back side of the butterfly.
Ends up pooling out the carb.
