Hesitation!

[KittyCamper84]

We have a 1984 1.9 DG with a Pierberg 2E carb. As you drive the camper, it has a hesitation. It only really goes if you press the pedal right down, otherwise the seems to be nothing. Being as it is a twin choke carb, it seems that only one is working? As a result, we are only getting 18mpg

Any help would be much appreciated!

hi there i had the same problem last year and it was the diapham pump was split on the carb . bought a new one from brickwerks . its on the carb with 4 screws holding it on check that shaun

would that control the pump jet? if it does, that works ok!

well if your accelerator pump works OK then you have an air leak on the induction side.
usual suspects are..
vacuum hoses to and from the distributor
vacuum hoses to and from the air filter housing
Brake servo vacuum pipe off the inlet manifold
Split gasket(s)
Choke pull down unit diaphragm split
