Lots of info there:

Also regarding too high idle:
http://viva-lancia.com/fulvia/qanda/carbs/high-idle.php

A gold mine of information really, with the caveat:
Carb tuning is complex and should not be left to the un-experienced. If carbs are properly tuned, Fulvias are extremely economical in terms of fuel consumption: the real problem is that often carbs are not properly set-up or tuned.

I think part of the problem is having replaced two carb mounts with a single carb mount that the throttle mechanism is now slightly fouling the single mount. Going to have to file a gap for it to return into.
Hopefully that wil get the idle under control.

Update, ALL of the problem was the single carb mount as opposed to the 2 x  carb mounts I had before. With the old mounts, there was space between them for the throttle mechanism to spring nicely back but not with the new single mount. I've now cut a notch into the single mount and the throttle works as it should.
The new mount cured the low rev hesitation and the car is driving nicely. Yes, I'm sure a little more carb tuning with a carb balancer will help performance or economy but I'm much happier with the way the car is driving. Grin

Now you can set about enjoying the car.

Really great news....so there will be at least 3 Fulvia Series 1 Berlinas next weekend. How exciting. And the forum has been very helpful I reckon - I have learned all sorts of Fulvia tips over the last couple of years in spite of what must be nearly 43 years of continuous Fulvia ownership!

Yes, definitely the forum pointed me in the right direction straight away so thanks for all of the contributions.

Next job will likely be a new possibly upgraded clutch for the 2C so I'll be asking the forum which is the best way to tackle that!

Any particular reason why? my clutch has been in for 14 years and 22,000 miles with no problems, but I'd better keep my fingers crossed after tempting fate like that Shocked

I just felt that after driving it for a while with the leaking carb mounts, it necessitated a lot of high rev pull offs just to get the car moving. At the time, I felt the clutch was beginning to get a little juddery. Now the carb mount is fixed, I can pull away with the minimum of revs and it feels ok but , with it having competed and me not knowing when it was last changed, I figured it would be a sensible move to change it at some point in the not too distant future.
I'd be interested to know what options there are available. I read somewhere on here that the Fiat Uno turbo clutch is a good alternative on the 1300 so maybe there is something similar for the 2C?

In the 70's our original 2C was used to tow a 21' Shetland cabin cruiser + outboard including going up and down ramps to float the boat off the trailer. We never had any issues with the efficiency or effectiveness of the clutch......however we did need to find spectators to sit on the front wings of the car when hauling the trailer + boat out of the water up the ramp due to front wheel slip with so much weight on the ball!
I never dared to calculate what the weight of boat + contents + trailer + engine was but we must have been breaking the rules by some margin.
