When the car is ideling (standing from the passenger side) the top left primary is spraying but not as much as I think it should. The top right primary is not spraying until I accelarate. While ideling the bottom left is dripping gas, about 2 drops every second. What would be the problem? I know, I just need a Sterling!!

Also if there is anyone that knows how to tune/rebuild a Nikki in Boise Idaho area please send me a pm. Thanks

 

The primaries are the little barrels, and the secondaries are the big ones. You shouldn't see anything from the secondaries. And there should be no dripping. At idle, you shouldn't see much at all.

 

Yes, the side that you see dripping fuel at idle is the side with the problem. How many threads are you starting for your carb anyway? Didn't I see a couple in the 1st gen section? If you can keep all info in one location it will help us to get you going again...

 

Ok, will do Kentetsu. What would be causing them to drip? Driving to school today it started to bog down really hard so I pulled over and both secondaries were dripping fuel. Could the needles be stuck causing the overflow of fuel to drip?

 

Yes.
When they are dripping, try rapping the carb with something like a hammer (without damaging anything).
Have you set the floats? Have you looked at the two sight glass windows in the front and the back of the carb? The fuel level should be about halfway up those windows. If not, your floats are set wrong, or the needles are sticking.

 

Are you running a stock fuel pump?

 

Yeah I am running a stock pump. I know I will need to replace it soon because when the owner had it the back fuel filter was clogged making the pump work twice as hard. Before I bought it I replaced the fuel filter and it ran fine, but I soon realized small air bubbles in the front filter. Could this be because the pump worked so hard it broke a seal causing it to suck in a little air?

And as far as the fuel level goes, it is right in the middle, maybe a slight higher.

 

Also I noticed that only one primary is pumping fuel at idle. Is this normal? It sprays when I open give it gas but I think it should be more.

 

At idle you really shouldn't see anything, only when you pump the throttle.
And, are the levels in BOTH windows halfway up?

 

At idle, the carb is using a different method for delivering the fuel, so you shouldn't see anything. What is your idle set at? If the idle was high enough, then it could be calling for more fuel, which you would see looking into the carb.

If the idle is set correctly, or at least under 1000 rpms, then you shouldn't see any gas entering the carb. If you do, then probably one of the float needles is no longer sealing properly. Time for a carb rebuild...

 

Yeah so i've got her idling at 900-1000 and there is still gas coming in from the top left primary. I'm just going to pull the carb off tonight and go over everything. Thanks for all the advice and i'll let you know how it ends up.

 

Ok so I took the carb off last night and to my suprise there is no weight in the valve coming from the AP. The ball is still there...but...........no weight, CRAP! Is there something comparative that I can buy from Holley or some other company? Or am I better off running to the local junk yard and yanking one from one there?

So with that still missing and a few other adjustments to the floats it is actually running better but doesn't like to idle when she is cold. After she is warm it runs at 1000 rpm with no problem BUT sitting at a stoplight, after 2 mins, she starts to bog down, and bounce between 500-700 rpm and then dies.

I would check the carb everytime I got back from something and I would say half of the time fuel was dripping from the secondaries and fuel remained dripping from the primaries for a short time after It was shut down.

The floats were adjusted and the fuel level is around 2-3mm above the line.

Should I just light her on fire and buy a Sterling?

 

Have you checked for any air/vacuum leaks? Fuel should not be dripping when idling.
And, BOTH sight glass windows are at half?
I bet if you look at both the windows while the carb is dripping and the engine is off, that at least one of those windows is completely full.

 

For that missing weight, contact Sterling. He'll know where to get one...
