Nikki pumping gas out of the secondaries
Like the title says, Gas is POURING out of the secondary venturis all the time. I just got done with a rebuild so I'm quite sure it's my fault but since I'm carb challenged, any ideas? I'd not have even started this as my record is now at 5 rebuilt and 0 succesfully but since sterling has had my carb for over a year and now doesn't even bother to answer my emails, I tried to get a running car. Anybody know a business that will rebuild a carb? Unless I can get this working I'm being held hostage by a supposedly reputable business for time and all eternity. Sorry for the vent, any help possible?

It still has intermittent float sticking issues but it's running some of the time so there is hope. I'm calling it half running so far. Good luck on your attempt.

Make sure the passage where the needles go is clear of crap and ooze (assuming new needles),
same goes for the float hinges. Sometimes I would dip the needle in some motor oil before
installing it. That allows it to have some lube for initial movement, and it never hurts the motor
to get some extra oil down its throat

dont forget the bowl vent solenoid , can add an issue with an overflow after shutdown from perculation
needs as a minimum to be bridged with 12v from the coils
( and not from the wrong side of any points ballast resister )

I'm still having float sticking problems. I've ordered a fuel pressure regulator which will hopefully get this issue gone. I'll add stuff in a day or two if I need to.

I did have a similar problem when i rebuilt my carb. Did you adjust the floats at all? I did that and it messed it all up. If ur not sure pop it off and at least double check to make sure that they are right. As for the fuel pressure if the pump worked before the rebuild with the carb no need to assume that its pumping out too much pressure now. I did see if you rub the new needles with ur fingers and some oil that helps to take down the rough edges and help them seat better and faster.

As far as the fuel pressure being right, I bought this carb from a junkyard and don't know anything about it. The car (maxton Rollersakte) had a dellorto on it when I bought it. The carb is brand new looking but all the gaskets were dry rotted and it would sort of run below 3500 rpm and wouldn't run above that at all. I got a rebuild kit for it and tried rebuilding it but my kid got into the basement and ran all over with the carb parts. 4 year olds do that kind of thing. Anyway, i rebuilt it but obviously some of the very small parts are gone and the car wouldn't run at all. As a side note, if anyone wants to buy a beautiful Dellorto and manifold and you have the expertise to get it going, you can have it really cheap.
Then I got a junkyard carb and sent it off to sterling with about $700 and figured I'd get a carb back to use. A year later, I've given up on ever actually having a sterling carb. He's stopped responding to my emails about any status updates. So,I got a "new" junkyard carb which I've rebuilt according to the instructions on sterlings website. Now I'm trying to get it to run. The regulator will go in monday and hopefully I'll have a running car.

I did the burnishing during the rebuild. I followed Sterling's website for closely. It's running at higher RPM's quite well, no load yet. When it gets to idle it runs terrible. I'm gonna search for a while on how to adjust an '80 for proper idle and get the throttle carble ends right and adjusted. Then drive it probably sometime tomorrow. It runs really smooth above 3K now. It's starting to look good for my rebuild to actually make it better.

I have a Holley fuel pressure regulator with a range of 1 to 4 psi. It is in the "factory setting" which is half way so about 2.5 or so. I'll be getting a gauge soon for it. I haven't had it over 3500 RPM yet. I read the tuning troubleshooting info on sterlings website and I've got everything setup to start fixing the idle tomorrow. The throttle cable has the carb end on it now so I have a gas pedal finally.
It ran so good I'm finally feeling pretty good on the chances of autocrossing it on sunday. Floats are still sticking but much less with the regulator.

if idle sucks,,and the carb is no longer obviously overflowing
just check that the PCV valve isnt jammed wide open making for a huge air bypass
it has a tapered seat so as not to flow massively at shut throttle and only takes a bit of carbon to stay stuck open and bugger up the idle

Why did you send Sterling $700.00? His carbs sell for just over $400.00
Just curious... As far as lack of email response, I do know that he's been having computer issues. Some kind of virus or something, changing the date on his computer so that his emails usually end up going straight into your trash bin (due to the date on the email). You might want to look in the trash and see if his replies are there.
Good luck. Awesome car by the way.
