For my zetec engine I'd really like to run twin carbs but I've seen for sale weber dcoe's and dellortos so my question is does anyone have experience of both types of carb and is one better suited than the other?

Webers if they have a fifth progression hole mate, are the best ones for a Zetec

Any of the Weber or dellorto carbs are fine for the zetec. As long as they have the 5th progression hole.
Personally, I like the dellortos. I like the noise they make over webers. It's ever so slightly different to Webers.

What are dellortos like for parts and maintenance?

I've found a pair of 45s from a 2.0 zetec hot rod and am very tempted to buy them but as I don't know about them I'm alittle nervous but from what I've read on other sites that use dellortos a lot like old lotus cars they seem to like them more than webers.....

No more difficult to get than webers.
Dellorto get a bit of bad press sadly. Just because Weber came first... Oh, and that dellorto essentially copied webers designs. Lol.

Euro carb do dellorto parts.
Fast roads cars . co . UK are good for parts too.

I loved having my 40's on the car.
It honestly broke my heart when I sold them. :(

But I couldn't run them on a daily car.
Just far too expensive on short runs.

As for maintainence...
I never had any issues with mine other than the misab gasket plates doing this....

Buy these instead....
( 2nd row and 3rd or 4th row )

They are a LOT better, and last a hell of a lot longer!

I also recommend the thackery washers over the rubber bobbins for the vibration mountings.
The bobbins can easily be over-tightened.
If you use feeler gauges with the thackery washers ( as you're supposed to ), it's nigh on impossible to over-tighten them.

The Thackery washers are a coil.
You put the feeler gauge in between the coils to check the tightness.

Do You mean You should set the tightnes to some level or just to a level where all washers are tightened the same way?

You need to tighten the nuts up to hold the carbs to the same level.
Bind levels differ depending on where you read.
Anything between 10 and 40 thou.
I'd go somewhere in the middle.

So where do You measure? Between the carb and the manifold or the carb and e.g. misab plates?

As Jason said, put the feeler gauge between the coil of the washer as you tighten the nut.

You measure the gap between the thackey binding.
