:(


i noticed today when i was fiddiling around that im not only getting a 1 sided pump shot from my accelerator pump from my bbd. so my dad told me to use a cuetip and put over the hole and and blast what ever is in there out. it slightly worked but just a weak stream came out.....then i took a paper clip and put in the hole.......it would free it up then i would pump it.. both...both....both....unclogged one...unclogged one and so forth. so either side works but not both at the same time. if your confused i understand.



what could be my problom?


ive looked for ideas in the great pdf file dan made...but i couldnt find any ideas


hopefully ill fiddle with it tomarrow.....so andy ideas are welcome :D

Your problem is most likely a worn out accelerator pump cup. This is a wear part that will wear out with time. Get a god rebuilt kit and replace the pump gasket.

maybe take the squirter nozzle off and see if there is trash in there. Don't do it on the motor as there is a check ball under there that when you hit the throttle. It can pop out and go down into the intake.
