now what????????

[burban J]

got an 85 burb, idles perfect but when under a load it hesitates at about half throttle. new fuel pump, plugs, cap, rotar, fuel filter. i even tried a completly diffrent distributer and rebuilt the carb.

Still running catalytic converter?? Maybe plugging up.

 

[burban J]

im not running any emission stuff at all

 

[gmtech954]

is it an electric controlled carb?

 

[burban J]

no electonics on this carb.
im starting to think the problem is in the carb but i have had it apart twice already
