the 600 1850 list holley on my model a has been dripping ( almost running sometimes) in from the boosters ....sometimes the rears ....mostly the fronts....rebuilt the thing earlier this week after it locked up when i hit the key.....the thing is ......it only does it after i get on it.....or do a good burnout....nice and smooth till after i let off it...and then it starts stumbling from the excess gas.....any ideas.....a little embarr***ing.......having to pull over after ya thrash on it.....thanks brandon
years ago i had 3 different one with the same problem. i never did figure out how to stop it (and i tried) so i tossed the damn things and started buying the Carter/Edelbrock carbs. never had a problem with them. worked great right out of the box.
usually i have problems with dirt and the needle and seats....blowing gas out the vent tubes.....i wish it was that easy .....lol first thought it was too much pressure.....but its just a stock pump....maybe bad floats....but they float....the float level is real low .....and still hasn't helped...maybe air bleed is blocked....? wrong metering plate gasket...??? ..thanks brandon
I would look at the metering block gasket. I got a bad one right outta the box a few years back. brand new Holley 600 w/ vac secondaries. damn near drove me nuts. had holes blocked that shoulda been open, and holes open that shoulda been blocked acted just like you are describing. maybe trash in the metering block has plugged some holes. just my .02 Vance
Brandon, I had a similar problem with an Edelbrock with a stock fuel pump. I couldn't find anything wrong until I finally checked the fuel pressure and it was putting out 16 PSI. You might throw a fuel pressure gauge on the car if you haven't checked the pressure. Larry T
will have to check pressure.....its sorta odd ....i set the float level ...just under the sight plug.....the first time it started doing this.....you could pull the sight plug and gas was pouring out.....like it was a bad needle and seat....but i would think it would be coming out the vent tube instead of the boosters.....right..???? brandon
I say dump the holley **** and get a weber, carter or something of that sort. If you have a power valve on it, getrid of that pile of **** with the installation of power valve eliminator.
....but i would think it would be coming out the vent tube instead of the boosters.....right..???? brandon[/QUOTE] Both, but it comes out of the boosters before it comes out of the vent tube. If the fuel level is just a little high, it'll drip out of the boosters and not the vent tube.

no! holley rules and hot roding was built on them.it sounds like the float level is too high if it drips out of the boosters.this is a touchy s.o.b and make sure the car is perfectly level while setting the float level.good luck and dont ditch the holley.
trust me on that ....it will have the holley waaaay before it will get a edelbrock....got too many holley parts layng around.....usually the 1850's are the easiest to work on and work well on a mild motor....the only thing thats going to replace it are a trio of small base rochesters.....lol brandon
Is this an older or newer casting? The later (last 2 or 3 years) are notorious for having problems. Its a ****shoot to get a decent 1850 out of them... either new or remanufactured. Their tech guys don't seem to want to help. One of my customers waited on hold for 35 minutes a few months ago. When he finally got through the tech guy just told him to return it. My customer insisted that he wanted to fix what was wrong... the tech guy basically told him he cant fix it and not to waste his time. Nice, huh...
Holley carbs rule... The post earlier about eliminating the power valve is not the way to go for a street driven car. The whole idea behind having the power valve is too improve the idle quality. I'm really not so sure I would remove it for a strip only car either. -Troy
ended up checking the pressure this morning......was showing almost 11 pounds....about 6 more than i was expecting....and this was a old stock pump ....so that leads me to think something inside is goofed....as it has been sitting probably 3 years ...i ended up switching to another pump.....haven't checked the pressure yet.....but after a good burn out.....it wasn't drippin' no more......hahahah as a side note.....did a search last nite on holley troubleshooting .....the instruction pdf i down loaded on a 1850 .....didn't show any troubleshooting at all.....hopefully the carb is back on the road to recovery .......brandon
The reason behind dumping the holley, Is I have had nothing but really ****ty luck with any of them. And yes their tech support was not the greatest as well. I just got tired of screwing with them, and getting ****d on parts. Although there is a ton of parts out there for them. My luck with holley has just ****ed. I understand the PV is supposed to help idle, but They sure ran a hell of alot better with out it, and I got tired of replacing them. Good luck with yours. Most of these were on 351 W pnched 30 to 60 over, a 302 and a 350 stock, and one punched 30 over. Heck we even had better luck with a quadra-junk rebuilt unit right outta the box, than a brand new holley. I never liked the Q-jet much, but my dad sure could tune the hell outta them. Anyhow looks like the fuel pressure was your enemy. have a good weekend.
I just put a fuel regulator on my 3 duece set up & it really helps alot.gotta figure at 70-80 mph that pump is really up there in pressure. I agree on the Holley-Carter debate, Holleys are great carbs, but are troublesome, as far as i'm concerned i'd rather have a reliable, trouble free carb then one that i have to **** with constantly. its like having a car that runs hot at times, you don't want to go anywhere cause your affraid of traffic. Also being 100 miles from your house & developing a gas leak can really be a problem!!especially on a car with a closed in engine. but for flat out racing you can't beat em. JimV
It's like Coke & Pepsi, chocolate or vanilla, light & dark...some folks prefer the Holley while others prefer the Carter/Weber/Edelbrock. The Holley is an outstanding carb & much more performance oriented and tuneable than the Carter/Weber/Edelbrock. Of course, you might need to know what you're doing & how a carb works to make it work right though... Using an Edlebrock is kinda like using windows on a PC...makes it so anyone can use a computer!
lol You are totally right Ernie. I do not prefer holley. There ae a ton of parts availiable for them, but sometimes I get tired of tinkering with ****. Its like when my wife wants me to eat fried chicken, or snow crab legs or U peel em shrimp. I tell her "baby I take **** apart and put it back together all day every day, the last thing I wanna do is take my freaking food apart to eat it." I have a couple of holley's still hangin out on the shelf here, maybe I will put them to use one day. As for windows, It and Bill Gates **** fat hairy donkey ****. I turned to the dark side of Mac, and will never go back to windows. I have no virus problems, no pop ups, and when I freaking delete junk email it is gone for good. It so nice everything just works, no downloading instaltion tools to help install ****, and no need for a billion drivers, all my video cameras, and cameras are plug n play, and just work. Its a breeze. I guess im just lazy in my old age. hahahaha
