Off topic: Holley carb accelerator pump circuit tuning

[Jim Jablonski <jim@xxxxxxxxxxxxx>]

Any Holley carb experts out there willing to give me a hand as I help my 
neighbor with his Chevy?  He installed an 800 double pumper right out of 
the box and now he has a mild stumble on light acceleration.

I looked down the primaries while slowly activating the throttle, and it 
looks like a series of inconsistent squirts instead of a distinct 
stream.  If it wasn't a brand new carb, I would recommend a new 
accelerator pump diaphragm, but like I said - this one is fresh out of a 
box.

Also, I noticed that the nut that adjusts the accelerator spring lever 
is quite loose.  I am not a Holley expert, but I thought that the more 
you loosen the nut, the more spring pressure is applied.

I would appreciate your thoughts.  Also, I don't want to break any 
clubhouse rules so I marked this off topic - I guess if it's for bowtie 
so maybe we should chat offline - although Holley tuning could be of 
general interest to the "team."

Thanks and regards,

Jim
