1978 Fiat X1/9 4 gear, 1290 with Weber dual float carb marked 22-22 made in Italy Bologne.
(can supply photos if that helps)
OK. Here's the story!
1) Rubber stopper burst - overheated.
2) Got new stopper no problem - finished long journey no problem.
3) NEXT DAY - THEN I had a problem! It didn't fire.
(battery OK, petrol pump OK, spark at ignition coil OK, distributor cap ok)
4) I pulled carb apart but DROPPED NEEDLE VALVE. (yeah OK - clever me!)
I found 2 parts, (3 if you include the square spring for float.. still on the needle)
5)a) I took to Fiat mechanic who discovered that even new spark plugs got wet - FLOODING!
5)b) He adjusted float quite a few times, even at minimum flow position, STILL FLOODED.

QUESTIONS:
1) How many parts to a needle valve (describe please?)
2) Anything else cause flooding?
3) Would taking spark plugs out for a few days help.
i.e. Can it dry out then simply go as easy as ever.
4) Anything else you can think of?
5) CAN ANYONE SUPPLY NEEDLE OR CARB KIT PLEASE?
International Auto Parts referred me to Pierce Manifolds who don't list such a low number.
6) Ideas for substitute carburetor please?

PLEASE HELP.

Try these guys

They are (amongst other makes) Weber specialists and have been one of the most reliable suppliers of spares for as long as I can remember.

I can't help with the other questions right now as I don't have much time (like I've got to get to work *now*!)

Thank you. REALLY appreciate you being so active in this forum.
Someone else put me on to www.piercemanifolds.com
