Holley 850 dp issue

Good Morning, ALL.

I have a question/small issue regarding my Holley 850;

When I am cruising at 10-MPH/@ 1000-rpm ... when I stab the gas pedal to 3000-RPM, the Buick PULLS HARD/SPINS TIRES ... but 2-seconds later it almost shuts off/looses idle.
It happened again yesterday near the garage. Why?


Are my squirters too small (size 31 ... "11-Second-Steve" uses size 41)???

 

Just to clarify: the stalling occurs AFTER you have let off the gas and are decelerating, correct? It's not a case of good power for 2 seconds and then it acts like it runs out of gas while you are still flooring it?

Running out of gas under acceleration can happen (acceleration pump/power valve problem), and so can running out when you hit the brakes, for different reasons (sloshing).

And how are your floats and their settings?

 

LARRY!!! "Always an Honor".

I just called "11-Second-Steve" regarding finding out if I have jet extensions in the rear bowl; got his voicemail ... he'll call me back with that answer.

It does happen ONLY when I come OFF the gas pedal after a 12-MPH roll in gear to 3500-RPM stab of the gas pedal.

Yes-Sir; happen AFTER I have let off the gas/decelerating.

Float levels are perfect.

LARRY ... "THANKS VERY MUCH AGAIN."

Steve just called me back; I will do as you suggested with the rubber vacuum hose tomorrow.

I am supposed to meet up with "11-Second-Steve" on Saturday with the Stage-1 (if it doesn't rain) ... I'll know how it works then.

o No:

 

Thanks very much, Larry; but how do I prevent the v-hose from getting injested into the motor?

o No:

 

If you are connecting the two vent tubes with a piece of hose, one way that I saw was to cut/drill a hole through your hose at the halfway point, so your air cleaner stud pokes up through the hose. That will hold the hose in place.

 

Thanks, very much.
