Way too fat, is my guess. Look at the linkage between the throttle arm and the barrel valve. You want to lean out the motor, so loosen the jam nuts on both ends, and lengthen the link by three flats or so, to start. Keep track of the moves you make. Start up the motor, and keep lengthening the adjustment till the rpms rise at least four to five hundred rpm over your normal idle rpm. This will be most likely lean enough to build heat in the motor. Once you have it to the temp you want to run at, fatten up the idle by shortening that link till the motor has instant throttle response. To warm the motor once you have the barrel valve set, push the fuel shutoff patially closed, keeping an eye on exhaust temp, or enough to raise the idle as before. You will notice the motor won't like to be real lean until you get some heat in it, so be patient, leaning out a little at a time with the shutoff as it warms up. Also, you probably have fuel draining out of the injector lines when you shut off the motor. When you shut the motor down, starve it to death with the fuel shutoff, then hit the starter again after about thirty seconds, and it will run a bit and burn off the fuel that drained into the cylinders. To restart, put the throttle to the floor, crank till it pops, quickly back off the throttle till it starts. May take five seconds or so. Keep the motor lean as much as you can to keep the fuel clear, and heat up the motor real good (210+) to clear the oil.

your dead fat for sure, like was posted lean out the barrel valve till you loose your throttle response then come back a flat or to till it returns. there is so much to a simple injection people often overlook the important things.
Did you leakdown the barrel valve before you started it? 20-25% is a good start with around .002-.005 of butterfly to runner clearence What are your pump flow numbers? What size nozzels are you using? what size main jet and whos jet is it? how much total horsepower do you think you will be making?

Yes my buddy did a leakdown on the barrel valve. Went by Kinsler book for my cubic inch and set it at 18%. Butterly clearance is at a tight .004 Enderle pump(new), not sure on flow numbers but was what Alky Digger recomended. I belive it's part #80A?? Not sure on nozzles but same thing, what was recommended by Mike @ Alky Digger. Mian jet was .070 and changed to .080 (Hilborn)and did get better but still seems real fat. H.P I am guessing approx 750-775 at crank.
Did not adjust/close off shutoff valve at all during fireup and idling, ran it full wide open all the time. Will that not make the idle come way up Idles at about 1300 the way it is now but seems real snappy on the throttle
Thanks Derrick

The 1st time for the day I use squirt a little gas in all 8 throttle bores on the terminators,and it fires right up if I remember to open the shut off valve. For the rest of the day I just open the shut off valve and be ready to pump the gas pedal(acts like one does when its running out of gas) a time or two till the engines catches up.Ron's sell a primer system to cure this problem,but there is not enough room for another tank to hold gas,don't want the added weight and don't have the spare$$$. So I have gotten used to it. PS Mine never milks the oil,the oil out of it looks just as clean as the oil out of my Lincoln. But I use my lean out valve to warm it up,and when its in the high 90's like the present I never have to lean it out. I think it might would stay around 175 degrees if I run let it run all day. Just called and checked the price of VP M5 $279.00 VP M1 $179.00 per drum.

I use around 3 gallons on first run,warm up ,tech,etc.The rest of the day 1/1/2 to 1/3/4, You have more hp.but 1 am over 3000 lb at 9.65et.I can run mine at home for 15/20 minutes on one gallon or less cold.The barrel valve either has a problem or your probably have 30 or more % leakdown,The main pill wont really affect it that much at idle. Keep lentghning the rod till you get a stumble when you snap the throttle then go back (richen one flat) then see what your leak down is,The % is figured on a graduation of the air in gauge ,if you dont maintain 100 lb pressure on that one you have to calculate % on a graduated basis,.Sorry so long ,this stuff is simple but difficult to explain.

If the idle was set with the motor cooler than the temp you run at, it is probably still too fat. You will use more alky if you are trying to run the car at a lower temp than say 180 to 190 degrees. I see about 500 degrees exhaust temp at idle, full warm ready to run at 185 degrees. My system varies by a flat or two on the barrel valve adjustment from hot summer to cool fall days. You can set the idle , just remember exactly what you did so you don't lose the base setting. From where you are at, I would warm the motor to operating temp, then lean it out a couple of flats and see if it is crisp when you snap the throttle open quickly. That is what you want. Move leaner till it doesn't have that crisp response at operating temp, then go back a little at a time till it does. You want it just barely rich enough to be vary responsive, no hesitation. You will get there, just keep working at it and you will get comfortable. It would be a good idea to print all the posts on this thread and keep them with you till working on the system becomes second nature.

Just talked to a Hillborn user 10.0 at 3300LB big block, His main pill(bypass)is 89.You really cant copy other tune ups as similar numbers will flow different but its in the ballpark.His barrel valve is set at 19%.
People would come by our pits and ask about my injection because we always quialified #1 or 2 or 3. I always talked to them, but never told the truth about my setup. It's racing, it's competitive. Why would I tell you my tuneup for free? Like what was said, everyones setup is different and if you listen to too many people your not gonna win or run worth a hoot. Get out there and run the car and make changes and don't worry about the other guy. You will never learn until you make changes and see how the car runs.
If it's milking the oil, it's not right and they are not made to idle for 15 minutes.
The best way to prime the motor is with gasoline in a presurized sprayer that atomizes the gas. Only need to do it when the motor is cold.

I haven't touched the linkage because my buddy told me not to $@#! with it
You are going to have to lean out the idle with the barrel valve linkage, or have somebody do it.
Everything you posted shows it is way too rich at idle. Including when you lean with the shut off valve the idle goes much higher. It is normal when leaning with the shut off valve for the idle to go up, and that actually helps driving in the pits (little/no throttle needed). And after adjusting the barrel valve, readjust the idle throttle blade position. Keep notes.
Don't confuse rich at idle and rich going down the track at WOT. You can adjust the idle with the barrel valve setting, and the WOT with the main bypass pill/jet.

www.hre.com and Spud Miller at Fuel Injection Enterproses have math formulas that will get you a starting baseline to work from. If your pump is an 80A, it's around a 6.8 gallon a minute pump. You are fat! With your cubic inches and the intake that you have, your fat. You could go to a 100 pill in the main, and it would be close I bet. The other thing that so far nobody mentioned is that when you change your main pill, if your barrel valve is spot on, you will have to adjust it a flat or two. Until you get close with your tune-up, you will want to make changes of 12 - 16 number on your main pill. You're looking to make heat in the motor and show heat on the plugs. Once you get close, then make changes of 4 numbers at a time: 100, 96, 92 or 100, 104, 108. Once your happy with how the car is running, then you might want to think about adding a high speed lean-out to further dial in the system.
