I'm as giddy as a schoolgirl (new sterling carb)

Just wanting to share my joy with everyone here. I just got my brand new Sterling carb from Carl, and its the absolute most beatiful thing I've ever seen. If anyone here is thinking about a carb upgrade DO THIS. Its a great value and you get awesome results. As soon as it's installed and running I'll let you all know how great it really is. For now drool over the pictures.

Thanks Carl, you're the man. You delivered even more than I expected.

Oh and on that last pic, what is that little outlet/inlet thing above the adjust screw? I can't remember and I dont have anything to connect to it. (was it something for the rat's nest?)

mmm clean carb

MattG 04-12-06 05:59 PM

You my friend are a skank!!!

I am still waiting in the 10+ week line!!

Rotaryhaven 04-12-06 06:03 PM

Damn, that is some bling, bling you got there, I am jealous! I wonder if they would rebuild an old 13B carb.

lovintha7 04-12-06 06:11 PM

They could probly hook you up with somethin Jerry. Reminds me of when I had my 12A and Sterling carb...mmmm

rbf41182gt 04-12-06 06:21 PM

wow, looks awesome

how long did you have to wait?

vipernicus42 04-12-06 06:36 PM

It's awesome looking. Looks so different from the one I had. And it has no return line. I always wondered how the heck that worked. My Mallory puts out 70gph at 6psi, regulated down to 4psi by the Holley FPR.

Without a return, I'd assume that either it's pushing back at the pump, or the car is burning all that!

I dunno.. just doesn't make sense to me. Wouldn't the pump be trying to pump but can't because there's nowhere for the fuel to go? Wouldn't that wear the pump out sooner?

Ya, how does that work with no return?

That carb looks GREAT with the mat finish and black linkage. I would get mine done that way if I could afford it.

1badFB 04-12-06 07:12 PM

In most cases, If a carburator doesnt have a return line, its probably meant to be used with an aftermarket adjustable fuel pressure regulator. In such a case, the regulator has a return line which bleeds off all the extra pressure and fuel. In the case of a stock nikki since there is no external regulator it is just sorta integrated, thus the reason for the return line at the carb. Am I right?

vipernicus42 04-12-06 07:18 PM

No FPR in the nikki! That's why I have to install an external.

And my external FPR is a returnless FPR as well!

those carbs are pieces of art in themselves. Very nice!

cdrad51 04-12-06 07:57 PM

Very nice piece of work Carl. I like the simple linkage and love that idle screw lol.

inuissus_cendi 04-12-06 08:25 PM

Yeah I'm wondering about the "no-return" thing as well. I dont have a return style-regulator, and I got the one Carl recommended (holley 1-4psi). I'm in the midst of installing it all right now. Summit sent me the wrong fuel filter though so I'm gonna have to stick my old stock one in there for the time being. I also dont have a fuel pressure gauge so I'm gonna make sure to keep the pressure REALLY low, especially without a return line. I dont want to have to deal with flooding...

But yeah, this thing is gorgeous. I didn't have to wait too long... cant remember when I sent it to him, January maybe? I told him to take his time though as I didnt need it until spring.

Great work Carl, and I'm loving the T-shirt. I'm proud to sport PB&J on my back.

So you're as happy as a little girl on jellybean island?, and rightly so.
That is nice.

From my interpretation of the rats nest removal, the inlet you are asking about gets capped, as in my drawing.

vipernicus42 04-12-06 11:23 PM

No idea what the inlet is for.

For FPR, my holley 1-4fpr is just set right smack in the middle (I actually screwed it all the way in and all the way out, counting the turns and put it right smack in the middle)

I figure that's gotta be damn close to 2psi. Then put the pressure "up" a bit (can't remember if that is screwing in or out, but the instructions were helpful). 'Cause you're aiming for 2.5-3ish.

Ran fine for a summer that way, but my Sterling had a return line.

Jon

inuissus_cendi 04-13-06 07:34 AM

I KNOW why theres no return (shit). I asked Carl to boost prep the carb so that if I decided to go turbo in the future (which I've been thinking about) the carb would still work fine. I forgot about the whole "no return line" thing. I'll have to see if I can get it back and reinstall that so my car doesnt flood as soon as I turn on the pump. :wallbash: And I was hoping to have her running last night... damn

bliffle 04-13-06 06:16 PM

Keep us informed. I've got a new Sterling ready to put into one of my FBs when I decide which one.

Kentetsu 04-13-06 07:23 PM

If you keep the return line, then the stock restrictor will help to adjust the fuel pressure somewhat. If you get rid of it, then your FPR will do it all by itself. The difference (according to Sterling, and I hope I get this right) is that without the return line, any adjustment made to the FPR will make a bigger difference. You can run it either way, but I decided to keep mine figuring that it would make it a little easier to make fine adjustments at the FPR.

cdrad51 04-13-06 07:36 PM

I ran my Sterling carb with no return line. No flood problems.

inuissus_cendi 04-13-06 08:02 PM

Really? you can actually run it with no return? Wow, you guys just made my day, hell my week. I thought for sure it would flood, and I would have to get the return part back. Wow I'm gonna go try it right now. :D I sure hope you guys arent making this up.

cdrad51 04-13-06 08:20 PM

Dead serious. Here's a pic to prove it.

Kentetsu 04-13-06 08:22 PM

Yeah, I think all of the new Sterlings come without them. Keeping mine was optional.

inuissus_cendi 04-13-06 08:31 PM

alright, I believe you guys. But now (I know... I'm a noob, but help me out please) I turn the pump on and within maybe 10 seconds the carb starts to flood. What should I do/check? First of all to get that fuel out of there... secondly to keep it from flooding again. I dont think it flooded too much cause I turned off the pump pretty quickly. HELP! (please?)

cdrad51 04-13-06 08:53 PM

turn down the goddamn pressure. What pressure are you running?

trochoid 04-13-06 09:09 PM

The carb will not flood if the fpr is set right. I've had trouble running a return line on the stock carbs with and an aftermarket pump and 1-4 psi Holley fpr. The pressure wouldn't stay up, it was bleed off by the return line. The barrel shaped fitting in the return line is a built in fpr. It is a one way valve. By turning it around, it makes the system retunless and keeps the pressure up for the fpr.

The carb may also be flooding due to a sticking needle and seat.
