To keep from having to type all this again some this I copy from other post. Please ask any questions 
So like to hear some input here about the set up.
I have try to run this 2 times now. once 1/8. once 1/4 mile. Carry good fuel pressure all the way though the 1/4 mile. Had all kind of dumb things go wrong with this carb. from wrong set up to needle&seats leaking to strip out bowl screws. idle circuit plug up. strip out squirter screws.. accelerator pumps not working. I think I got everything fixed. little about the car first. 3600lbs- footbrake-30 over 440- eddy heads-590MP cam- cars runs 11.0s 1/4 mile 6.90 1/8 mile. I have had a Q/F 850 on it for years Done very well with it. This carb is a 950HP build by well know carb builder with e-85 carbs .I bought it second hand.Right now it has 84-94 jets and a 4.5 power valve in front. 30cc pumps with pink cams and 45 squirters. Might be a tad rich at idle ..might just be me not use to it. sits and idles great. have to idle it down to 900 rpms to get the idle fuel mixter screws to do anything ? but they do work. about 1200 rpms they don't seem to do anything. has IAB .067 and HSB .028. So does this sounds close ??
So it was lean.. hesitate.. ran hot.. so I jetted it up to 87-98.. and put .055 squirters in it and move the pump cams to #2 hole. still got some hesitation..so tomorrow I going to put brown cams on it and maybe bigger squirters. might jet the front up some more..But on the good side of it.It has been a while since I drove and I got in the gambler race and won it ! LOL
Now back to this Carb,,Not sure I like it !! the driveability Of this thing $ucks..way too cold blooded and once it wram up trying to give it light throttle it hesitation trying to just move the car a little in the staging lanes the Rpms drop down to far it dies..say below 700-800. It will once warm sit there and idle at 150 deg all day long. but over all it don't run cooler . It is a little slower and and so far I do not see it more consistent. I got away from the hesitation on the line by raising the launch rpms by 300 rpms But that makes it way to easy to red eye..Not good. I now have 90-97 jets and .055 squirters in it with pink cam on #2 hole.Dumping alot of fuel in there. after the run turn off the track look at the Temp it is 205 degs ..180 when I stage 150 pulling in to the water box.I am bout to put 50cc pumps on it ! Not sure what else to do to it
Well mine is a 950HP..We will get there I keep reading and it will all sink in sooner or later LOL.I do believe that part of problem is in the air bleeds. but do not know for sure what way to go..Dang gone thing sits there and idles so well I hate to mess with the IAB
