Hello,
Can someone explain this paragraph to me....
QUESTION My vehicle has a stumble from a dead stop. What can I do to cure this?
ANSWER The most common cause of a stumble is not having an adequate accelerator pump shot. The first thing to do is to look at the discharge nozzle and make sure you are getting a good strong pump shot. If not then you need to inspect the pump diaphram for a hole or tear. You will also need to make sure that the pump passage is clear from any trash or debris. First you will need to check the adjustment on the pump. To do this you will open the throttle all the way (WOT). Push the pump arm lever down and then adjust the pump override spring to obtain .015" clearance between the pump arm and lever. If you are having a stumble and no black smoke out the tailpipe then you will need to increase the shooter size. If it stumbles and you are getting black smoke from the tailpipe then it will be nessasary to decrease the shooter size.
so my question is the last 2 sentences....*increase the shooter size*..*decrease the shooter size* are they refering to the accelerator pump discharge nozzle(squirter)?I have stumble at initial accelreration...and i have a good squirt.My Nozzle is an .031...should I go up to a .032?Also...in the paragraph(this makes no sense to me??)The say to check the adjustment of the pump...moce throttle to WOT...There should be a .015 between the pump arm and lever?How can this be...wide open throttle is pushing down on the lever??No gap..0....does this make sense what i'm saying?Thanks for the help..bm
