Needle seat springs
1 Attachment(s)
I have recently had problems with the float bowls on my 80s Nikki randomly overfilling. It can happen at anytime, even while driving (noticeable by a slight stumble while at cruise, then it stalls with the clutch out). I can sometimes restart it, but usually I have to pull over and tap the air horn banjo bolts.
The problem was apparently sticky needles. I finally opened the air horn up and low and behold... no retainer clips! That is the first obvious thing I noticed. It causes the needles to randomly jam up and overflow the bowl with an erratic drip of fuel. I can fix this by finding some clips... BTW The carb was sent out to be rebuilt professionally by a shop about a year and a half / 1000 miles ago and cost the original owner $800!! But possibly related, I also noticed that I am missing one of the springy looking assemblies near the front float. Is this required? It seems like one of my old carbs had two, but this one only has one. I borrowed a picture from a fellow forum member :D Attachment 658371 |
Thats an 80 SA Nikki (cause I know its DDs carb) but later carbs I don't think have those spring
things in them. Curious to know the answer. |
Those long springs could be part of the power valve circuit found on automatic trans models. Anyone know for sure?

There is like a little shrewder valve in the rear float bowl that it connects to. Car is 5 speed.
