Thread: Fuel is pouring out of secondarys! What's wrong???

Tweet

......wow, just when I get one thing settled something else comes up! ..... Anyway, after I shut my engine off I looked in the carb & fuel is pouring out of the secondary's {the back two barrels}. It runs out for about 10 seconds or so & then stops! Any ideas on what's wrong??? THANKS Everyone, Bill

I find that happens quite often if the spark plugs are too short

What kind of Carb??? If it's a dual feed Holley, probably a stuck needle and seat

....Dave, yes it's a 750 Double pumper... I will go to their web site & see what it shows me as to where the needle & seat are.... THANKS Bill

Just under the adjustment screw on top of the secondary fuel bowl. It's a disease called Holleyitis.....

.....Holleyitis, he,he,he.... ... So I take off the big screw that I see at the back of {& on top} the secondary fuel bowl??? Then what??? What does it look like??? I went to the web site but it didn't point out a needle or seat.... Bill

Well, the needle will have a small v shaped neoprene on it, and the seat will hopefully be a circle that the needle will go into. Take the secondary bowl off, raise the float up and blow into the fuel inlet. It should not allow air through with the needle seated. Doesn't take a very big piece of dirt to make one of these little boogers stick!!!! Check it close. At my age and deteriorated vision a magnifying glass is essential!!!!!!

..... Thanks Dave, let me go try that Bill

Dont get so down I hear they work pretty good once you get them tuned in.

If that isn't it, it will be the rubber O ring that seals the needle and seat assembly.

Oops, forgot to mention that dang O-ring..... Thanks!!!!!

Had to replace both of them on a 650DP a few years ago on the road, ethanol ate em up.

I had the same problem and it turned out to be the screws in the meatering plate had backed out and would NOT lett the float go all the way up

.....THANKS Everyone, later today I'm going to pull the secondary bowl off & see what I can find. I'll check the needle, seat & O ring. Other than what you guys tell me I have NO idea what I'm doing. I just have visions of all these parts & springs flying out when I pull the bowl off! .... Oh I did read on the Holley web site & a couple of others so at least I know what the needle & seat look like & I see that 4 bolts take the bowl off... Oh I forgot to mention that this motor only has 200 miles on it. Plus it was dyno tuned in September of '06 {where it ran fine} & the Carb Shop rebuilt the carb {Sept. of '06} so I don't think any parts have worn out. The car sat after the fuel cell was installed {installed 2 years ago}. My Dad said that some dirt probably got into the fuel cell then got through the fuel filter & got into the needle & seat assembly.... He's forgotten more about cars than I know. Only problem is the last carb he rebuilt was on a flathead Ford 65 years ago..... Thanks again Everyone! Bill
