I'm sure you know that already though. I've also had no problems with the Holley HP 950. LIFE IS A LESSON,YOU LEARN IT WHEN YOUR THROUGH!

Nicest carb I have ever had Faster than any even custom HP 4150 carb I tried, and ran as well as a custom dominator. I tried a number of carbs Last edited by B3422W5; 09/28/13 11:05 AM.

It came back a immediately went 03 and 3mph slower. I tried thru tuning to get it back. I was able to get half of it back. In the end I called QF and ask if they could/would put it back like it was. I sent it back. When it returned. The car ran just like it did before I ever sent the carb to QF. Sometimes carbs are very good just as they were built. JMO

I checked everything, then I took a look at the arm that pushes down the acc pump lever. The arm appeared to be bent a little sloppy, not nice 90*bends. I took it off, tweaked it a little and replaced it. The carb works great now. My point is maybe it is not always something internal, check the most basic parts first. Carb was a Holley 4150 1k annular.

Does it have an adveance curve or locked out. 5 seconds... really. None of the 850 or 950 ultras I've dealt with had much in the way of tuning issues. The 80496 950hp's are horrible on cruise and require major tweaking to get a decent A/F. IMO, you aren't going to find anything out of the box that will perform spot on. Everything will require some tweaking. It's not a box stock 375hp 440 where the dealer has a carb on the shelf that runs on thousands of them out there.

The 750hp was a factory carb I bought and set up and the other 2 were custom builds.Some people have good luck with custom built carbs but I haven't. 77 Aspen R/T 60'@1.41 10.76 @ 123.26 http://www.youtube.com/watch?v=Eya3Ue8KoZk

I dont expect to get a carb that is perfect out of the box..............You should maybe change some jets,squirters,air bleeds?The 850 ultra I had had every tuning part changed and it still was crap.I gave a good effort to get it right.I did a search on here and found another guy who had exactly the same problems with a friends 850.Many the same on Yellow Bullet as well,not just me. 410 pump gas solis flat tappet cam 10.95 so far
