x2... seems like a real good idea..
but they don't have them for Qjets "yet" ??
not sure if they will, hard to improve on perfection, lol...
.
many people don't realize that 1- 30cc accelerator pump shot is 1.01oz of fuel...
that's a lot of ounces per day when driving, it adds up to gas mileage...
.
for years I been saying instead of just upping the squirter size when you have a bog/carb problem,,
find out what the problem is, what changed?? do some testing,,
before you start turnin screws... even the idle screw...
less could be better, if everything is right...

30cc,, that's a full shot,
holding the pedal to the floor till the squirters stop..
the accelerator pump is spring loaded,
so you don't get a full shot just stabbing the throttle and letting off..
depending on squirter size, it may last longer or shorter...
.
and a Holley "Double Puddle Dumper" has 2...
and some Big Holleys can have 1 or 2 50cc Accelerator Pumps..

@JJLT1 Well, sometimes I need the 2 50CC shots.
Like when going from sea level up 1,000 feet to the house.
Sometimes, this old truck needs a little boost up the hill. Like changing the vacuum gauge from -9 to +5 for a full second.
It looks kind of like this.

If you pay for it with pennies you kept in the car, you might see a slight boost due to weight reduction. Other than that, I’m very skeptical of supposed infomercial engineers who claim to be smarter than all the real engineers employed by Holley and Edelbrock, not to mention the Rochester Division of GM.
