Is there supposed to be green stuff stuck on the carbie needles?

needles in the mc22 are stainless or something, but the jets are brass so maybe from there, but I think needles are supposed to be clean.

nice one, I wouldn't have thought the needles would have affected starting though...
Well considering the only needles you get in Carbys are idle mixture Screws (needles). Then it would make a huge difference.banana.logic said:
Also check that the little holes in the emulsion tubes are clean as well. And the main jets located at a port from the float bowl.

I was thinking of the needle attached the the slide...
I thought that was called a needle jet, and the idle mixture was the mixture screw?

i think you need to brush up carb basics 101ASTAR said:
idle mixture screw is not a needle
needle is in the middle of the carb in the centre of the slide
and yes any crud on that is going to cause greif as the needle works in the bottome end so will affect starting and low throttle

johnnie, the idle mixture screw does have a needle on the end which can be adjusted by screwing it in and out, this may be what astar was referring to... but as per my above post, I wouldn't call it a needle.

So Carb 101 for me then. So guys are you going to teach me such things? :hail:
I suppose I was wrong with the only needle in this particular carby. But Idle mixture screws generally are a needle and the term "screw" is the adjustment method used on them.
Older carbies used to have these two components seperate - but in the last 15 years they have combined them as one unit. But for me being in the automotive business for 15 years - I guess I'm still old school with some of these terms.
My topic was only based on the idle mixture Screw(needle) - and nothing else.
So how was my reference wrong?
