|
|
I am trying to change the main jets in my 42 DCNF carbs (Berg version).
I can't get the jets out of the ends of the tubes.
Does anyone have any suggestions?
Thanks. |

The main jets are a press-fit into the bottom of the jet stack. Since you are not able to remove them by hand using a twisting-out motion, maybe heat up all the stacks in a boiling pot of water, take one out with tweezers, grip the stack with a glove and try twisting the main jet out with another glove?
I would try to avoid gripping the sides of the mains with pliers unless you put a layer of duct tape on the plier jaws so you don't gouge the brass jet material.

I run a similar 40DCNF on my 1835cc engine.
I remember taking off the carb top in 1976 soon after I got it, to change out the main jets, and confirm they just pulled out after unscrewing the "stack". I haven't taken that carb apart or off the manifold since, so I can't add anything more. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each. The '71 now has the 1835 engine, swapped from the '70. Second owner of each. 1988 Mazda B2200 truck, 1998 Frontier, 2014 Yukon, 2004 Frontier King Cab.
