BG Demon Carbs are WORTHLESS!!!

[72step]

Well, I got the second Demon in this week after the first one was defective. This one wouldn't even run. The front float was defective on this one. It was just pouring fuel in there and it wouldn't idle. The float adjustment wouldn't do anything. After messing with it for nearly 2 hours I finally took it off and put it back in the box. The first one ran real well but was leaking fuel. These things are overrated and really suck. I can't believe how junky they are. Man I'm pissed. Now I'm considering a Quick Fuel, or a ProForm. Anyone had one of these??? Thanks.

Was the front float saturated, or the needle and seat stuck open? How much fuel pressure are you seeing at the carb?

Holley street avenger carbs are nice pieces, Summit carries them

hmmm..... Thats a good point.

I only gave them one try. There are some that say good things but, IMO they are having too many problems.

It's just really dissapointing that they had such a good name going for them when they were upgrading the holley carbs.

[cooters]

between demon, and street avenger, i dont know which one is a bigger piece of crap. Neither one is worth the aluminum they are made from. No matter what, they require 20 hours of screwing around to make them work but the box says bolt on and go!

[1BadSS]

Sound's like you've got junk in your gas tank and it's clogging the needle and seat. 95% of part malfunctions are operator error.

I have a 650 Speed Demon (vacuum secondaries) on my 68. I bought it on e-bay. I haven't had to fool with it at all, except for a heavier secondary spring. It has been a great carb, no problems at all

[Bishops Trucks]

I haven't had any problems out of my 650 either. Tuned it in in 20 minutes and its been going strong for 2 years now. I've never been struck by lightning from using one of these carbs either. My Dads Dodge Demon is still rolling down the road after all these years to.

i guess is a bad first impression. lol

so you would buy something based on name rather than quality?

i have 2 "praise jesus" 680 cfms for sale, $500 each, youll be first in line correct?

[72step]

The name thing did cross my mind of them although I am christian but not very religious! No there's no crap in my tank, and fuel pressure has never been a issue, I'm running a mechanical pump. When I took off the screw and nut that turns the float adjustment, I found that that brass deal that the nut turns was like frozen, the nut wasn't turning anything, the nut was actually stripped because of the frozen brass adjustment deal. Also the first demon after I first started it and did the initial tuning it was hitting pretty close and this one was like backfiring and acting starved for fuel. Then when I started to slowly turn the float adjustment nut clockwise the glass window went from like 2/3 full to all the way full and after that it never did run again, who knows. I could see 1 defective product but two in a row? Come on! The first carb ran great and probably only needed a gasket for the leak, but I didn't pay nearly 500 bucks for a "project carb" It actually might have been warped.

[70c10]

These carbs like more advance than other carbs. My Demon likes about 19 degrees initial and 42 total. It works awesome and has a held a tune for two years How much advance do you have???

[72step]

I adjusted my timing to 19 degrees too. I followed the dvd and instruction manual to the T. I watched the DVD like 3 times before I attempted installing the first one.

I'm sure you have seen this but I'll post it anyway:http://www.barrygrant.com/demon/default.aspx?page=28
Sorry to hear about your problems though.

I have a 770 street Avenger thats been on my truck for 4 years...never a problem. I have a friend that has a BG Demon carb on a 427 in his Nova...again, never a problem. Maybe operator error?

[72step]

Thanks 70C10, I'm all too familiar with that BG troubleshooting page! All I can say is BG has quality control issues. Happens to a lot of U.S.A. companys once they get a good reputation, they start leaning on their reputation a little too much. I'm really leaning towards QuickFuel, I hear their customer support is great and their carbs are even better.

Nothing like a joke to lighten things up, although it seems that this one had the opposite effect. I thought it was funny.

The name did deter me initially, but it is just a name, a gimmick if you will. I am glad it didn't derail my plans. I got a great deal on mine.

72 Step, good luck with quickfuel, I hear they are great carbs as well. Have you considered fuel injection?

Very cool truck, by the way!!!

I had a leaky Demon 750,vac sec carb. It was a good unit, for the first 800 miles or so. Then the leaks, sticking floats...and then two of the heli-coil inserts in the main body stripped out. Below is the best fix possible, a Proform main body, with the original Demon metering blocks, bowls, and repaired baseplate. The Proform main body feature adjustable screw in air bleeds, same four corner idle...same features as the Mighty Demon units. This was my first Proform product...I always thought they were cheap junk The castings are VERY good, more features than the Speed Demon, cost under $100, and its an easy swap! And there is no choke tower...which I likalot!!!

-Begin rant-
I have had my Road Demon Jr. for about a year and have never been able to get it dialed in. I don't profess to be a carb guru but I know how to read (the manual) and follow instructions & have tried many times. I also called tech support and they more or less brushed me off. By that I mean the rep acted like he didn't want to talk to me and I had to pry any information out of him. I wasn't impressed. Iv'e changed the timing, tried two different intakes, removed the electric pump and installed a manual, etc, etc. Still runs like crap, If you set it so it starts it doesn't run good and if you set it so it runs good it's hard to start. It ran much better with the original Q-jet on it so that is what's going back on this spring. My suggestion would be to spend $100 and get your Q-jet rebuilt and spend the extra $200 on something really useful.... -End rant- ...

Just my 2¢ worth (from experience)

I am leaning to quick fuel also with there ss series you can get choke and vac secondaries.

[Psycho71]

I'm going to go out on a limb here, and say that most of these "problem carbs" were probably shipped UPS, right? Has anyone taken into account how UPS treats their packages when in shipment? This obviously wouldn't change anything after they've worked good for a period of time but, to me, would definitely account for float issues, and the like, right out of the box.

I have zero experience with BG carbs, as I have always had good luck with Holley. I have seen them get their share of ripping on here to. I even recall a thread ripping a few Edle's on here a week or so ago. And we all know the issues a Q-jet can have.

Obviously it sux to have problems with anything we've just spent hard earned money on. I prefer Holley, but will not dismiss another brand just because of the name stamped on it, or because a few people have had problems. If we did that, we'd couldn't ever buy anything. I will say this, the Holley tech line is great! They are very helpful and can point you in the right direction the first time, most of the time. I guess it comes from leading the industry for decades.

My Street avenger did require some tuning. But that's OK with me too. I like to know that the piece I put on a motor might require some tuning to match my application, and not just work OK for anything I might put it on. Even after UPS delivered it, I didn't even have to turn a screw on the floats. They were preset, like they claim. I just had to adjust the choke, hook up the vacuum gauge and set the mixture. Been good for over a year now.

As for the religious implications, not being a religious person, I think some people are way too sensitive. Or loose their sense of humor when religion is involved. Lighten up, god won't send you to hell for giggling. If he does, then he's the one with no sense of humor. And we know that's not true, look at all of the ugly people in the world.

Before you buy a proform main body(they're OK) you can buy a Holley HP main body for 20 bucks more...It is what the proform was copied(stolen) from. And it's made in the USA
