Mike...Do you run it thru the whole system? 
Yet.. fire it up and run it out of fuel(I put maybe
1 gal of gas in) run the engine till it runs out or
gets warm... pour in the fresh e-85 the day before
I head to the track and run it till its warm

what kind of ignition? i had the same problem coming off the 2 step.
I have learned that more heat in the motor will help that problem. Only time I have had that issue is in the cooler weather.
That's why I think all the fretting over seasonal changes to the blend are an overreaction. Your engine might just like the lower ethanol content in cold weather, that is why they change it after all.

AJ Casini was doing conversions also. He seemed to be VERY knowledgeable with E 85 I like the fuel, cheaper and more torque  Don

I don't know I have tried about everything you can imagine. come to find out the dig 6 is not recommended for alcohol/methanol and anything over 11:1 compression so that may be the problem. the volume of fuel may be to much for it to overcome coming off the 2 step for a split second.

Been running it for 2 years now .would never go back.,
same here for 1 season, will probably switch the arrow over this year. the cost saving is a bunch.

it's quite the combination-accell 300 box,msd dist.,Jacobs coil.i had eric build the carb for my engine-car combo and worked right out of the box.i would save up until I could afford a carb built by someone that knows e-85 before I would do the kit.

Why do you need to buy a carb from someone? What are they doing with it? Why? What is the theory behind this? I know the quantities go up with E-85, and you have to have bigger jets, this should be a calculation. Why can't I modify my carb? Is there a "secret hole" that has to be drilled? I have been working on carbs for over 45 years, I'm not new. I have some max wedge carbs I am going to try this with, but I am going with bigger jets. Should I send my carb to some expert to modify? I think I can put these together with my eyes closed, what do "they" know that I cannot learn? Isn't the whole theory just that there is 70% the energy of gas in alcohol. The AF ratio is different as well. I have seen these threads everywhere but NEVER have seen the "whys". Here is a big question, what do you do with the timing? I could go to the track and figure this out I guess. So, if we can state the theroy here, in this thread, we can all learn, and don't have to go to some "expert" who is no smarter than any of us, eh?

I'm not sure who told you that, but I don't really agree. Lots of guys running digital 6 (including me) on turbo E85 cars. The boosted motors need a lot of spark because it tends to get "blown out" under high pressure.

Well two things here.
1) Getting max rich right under WOT under most RPM ranges is not that hard. Like you said it's just adding fuel. The problem is though making the fuel curve flat is more then just putting a big hole in it. Both HSAB's and emulsion holes are changed on E85 carbs to get it right. Not to say you can't do that, but for me I was willing to pay for someones knowledge on that part.
2) The other issue is knowing the limitation of the carb itself that you're starting with. I know on my carb specifically it had a booster change, as well as having the mainwell size changed to support enough fuel flow. The main well change then dictated specific emulsion changes to go with it to get the fuel to pull up the main well.
I can tell you that Eric from Horsepower innovations services anesthesiology equipment for a living. Obviously gas flow is EXTREMELY critical in that field. He has a VERY good understanding of gas flow, and some incredible equipment to do testing/measurement with that most people don't have access to.
I'm sure there are plenty of guys out there that are converting from home though. I was just willing to pay for the "bolt on and go" carb. Especially because I didn't have one to start with, so it wasn't that much of a stretch to pay for when starting from scratch anyway.
By the way, Mike my fuel system was all 100% brand new (including the tank). I'm really not sure why it gummed up like it did.

Not that the "experts" are any smarter,but experience is a great source of information.There are many things we have learned from AJ Casini about E-85.
E-85 blends are not cosistant
Fuel system componants must be alcohol compatable.pumps,regulaters,filters,seals,gaskets,needle valves,etc.
Jetting,airbleeds and emulsion wells in the metering plates must be calibrated for E-85.
Engine temperture is critical.
fuel delivery needs to be adjusted(pump volume,cams,and squirters as well as primary to secendary linkage ratios).
The good thing with those who have had experience and success with E-85 can get you your starting point or baseline.
As many know AJ has been running this stuff for years and has been a consistant winner with his cars and has successfully tuned many other racers.At BGR, AJ Casini is our"go to guy"for E-85.

I have talked to quite a few racers who use either Lucas ethanol fuel treatment or Seafoam fuel treatment as an additive to keep the gumming down. Most are turbo cars,blow thru and efi both. They complained about needing to clean injectors or carbs often. After using these products, they said the problem was greatly reduced. Just thought this info might be usefull.
I ran mine all last year and seen no gum at all, over the winter I drained the fuel out of the tank but left some in the carb for 2 months. pulled it apart the other day and seen just a little bit of clear looking gel. took me about a minute to clean it. the pump had nothing in it all all. the regulator had very little. put fuel back in the tank and fired it up. just as crisp as ever like said before maybe it has something to do with blends, down here it has always been the same. mine runs from 85%-90%. stored mine in a drum, opened it and retested after setting 2 months and was still 90%. forgot I do add top lube so maybe that has something to do with it?
