Probably, the OEM needles and seats fail by sticking open. You should also check for wear in the floats and their pivot pin. The plastic and brass floats are particularly subject to wear in the brass section that will cause binding.

That sounds a lot like a Grose Jet. It's a replacement for the OEM float valve. Varnish build-up causes them to stick closed. If they do stick, you can cure it with a little carb cleaner. Some people like them, others hate them. Personally, I'd rather have the valve stick closed.  

The current OEM replacement valves seem to work very well and alleviate at least some of the justification for the Grose Jets..
