View Full Version : Edelbrock 1400 floods when climbing

The other day when wheelin', my carb was flooding even on moderate hills. I just had the carb installed with the new engine and I'm sure it needs more tuning. AzFrank was telling me that some carbs have an off-road kit available to help with this problem. Does anyone know if they make one for the EDL-1400, and what the model# is? I gotta' do something soon, I leave for a deer hunt in Grand Canyon country this Thursday.
The 1405/06 series have an offroad kit avail but I don't know about the 1400 series? You might try lowering the float level some. It helps on the 05/06 carbs. You might also dig through Edelbrocks web site. There's an online manual for the 1405 carbs on there so there may be something for the 1400's too. It's been awhile but I've gotten solid answers to tech probs from them by emailing them. They usually responded in about 24hrs. Worth a try.

I have never had a need for the offroad kit in my 1406, I have gone upp some super steep hills. Although it is kinda set to the lean side because of the altitude.
I would try leaning it out a bit and lower the floats like joe said. This generally helps a decent amount.
The 1400 is a 1406 with a provision for Chevy style EGR. The off road needle and seat kit will work in it. Go to www.edelbrock.com (http://www.edelbrock.com) and look up under their carb accessories lists for the part number.

Thanx guys! I just spoke to Edelbrock technical assistance and he told me to adjust my float to 1/2" (absolutely no lower). I guess they don't make an off-road kit for the 1400.

Edelbrock is right about adjusting the float, but wrong about not having off-road needle & seat assembly for your carb. It's the same carb as every other AFB-type, and these needles are spring-loaded so as to be less affected by fuel slosh.
I have a Carter AFB-9635, which is virutally identical to the Edelbrock 1400. In fact, I've put Edelbrock parts in it such as the off-road needle & seat assemblies and narrower jets (for atltitude).
As much a perfectionist as I am, I learned during the FSJ Invasion just how important float level is when I failed to make it up Imogene Pass after several attemps (and after watching several other guys make it). Later I adjusted the float, and voila! Up the hills I go!
I got the off road needles and seats in my wag on a Edelbrock 1400. Proofs in the Puddin'!
I gotta back Ralph up on that one. Imogene was a big pooh stick when the floats aren't adjusted right. We even had them high altitude metering jets and rods. Maybe it was the vacuum leak....
I also know a couple other folk with the same (1400 with off-road needles and seats)

Okay, i just got the story on this one. As you guys have been saying, the 1465 needle and seat kit will work just fine. The 1400 carb is an emmissions legal unit and cannot legally be altered in any way. That's why Edelbrock technical assistance can't suggest the use of 1465 kit. Do you guys think I should use the kit plus adjust the float? Or is the kit sufficient enough?

What? For Cali maybe, but not for most states I would think!! Gee you know that off-road needle really drastically changes everything in the carb!!

You will most likely have to adjust the float level when you install the off road kit. I had to move mine in a big way. Be sure to pay strict attention to the instructions on where to bend the float arms. I think this is where a few guys went wrong in Colorado. Their floats were not level or the arm was not closing the seat because they had not been bent in the proper spot. Take your time. I did as it was my first adventure doing this, and I came from Chicago all the way to the top of Imogene with only a timing change and minor tweaking on the adjustment screws. I didn't even re-jet!! Ask anyone who saw me, I did not stumble, load up or sputter the whole time!! Plenty of power, too!!
It is alot of fun driving those trails with a set up working properly !!

Okay I am convinced. I am going to put my holly 2bbl projection unit on my truck. I will have to pull it off the Mustang first but I think it will be worth it. i know in my mustang the mileage and performance both increased.
I have the stock carb not. Not gone up any big hills yet so I can't say if I will have problems. I saw Tom take on a hill earlier this year that caused a Chevy to die over and over again. That was before his rebuild.

What? For Cali maybe, but not for most states I would think!! Gee you know that off-road needle really drastically changes everything in the carb!! Maricopa County, AZ closely patterns their emmissions requirements to California. One big difference is we can get a one-time, one year waiver when we hit $400 of provable receipts to repair emmissions problem. All costs have to be directly related to emmissions. Another is that they won't catch that I have a 4-barrel carb on a vehicle that shouldn't unless I don't pass the actual smog test. But yes, they are true Nazis!
Also, where would I find instructions to properly bend adjust float?

The CARB(California Air Resources Board) EO (Exemption Order) number, #D-215-10 was obtained for the 1400 carb on Chevy V8 engines 1980 and earlier.
If your county is following California rules and you're putting it on an AMC V8, it's still not smog legal.
Besides, who's going to be able to tell you put the needles and seats in that carb? It doesn't affect your tailpipe emissions. Edelbrock just didn't want to spend the money to get another CARB EO number with the carb modified like that.
