I`ve just converted from a Pinto to Zetec and I am still using my weber 45`s. The car is running (with megajolt) but when revved the revs seem to stick and creep back down slowly. It`s not crisp and responsive. I also can`t get the car to tick over less than 1400rpm and ideally it needs to be about 900rpm. So, has anyone got an idiots guide on how to tune webers in 3 simple steps etc? i.e. what jet/screws to turn on the carbs and in what order to do things. Any help would be much appreciated. Thanks
Nick

Are you sure it does not have an air leak at the manifold? The slow return to idle (and the high idle) could be caused by that.
And I'm not sure there will be an easy tuning option for you, the carbs might need rejetted to suit the zetec

Cheers

It may be a while before it is of use but PPC are running a set of articles over the next few issues showing how to rebuild a used set of webbers.

I would have thought they will run an article on setting them up once they have finished the rebuild. It could be a couple of months before they do though.

Look in the downloads section of my website and you will find a few useful bits.

Jetting calculator for DCOEs (used it to base the starting jets on mine with, seems to run well at the moment, if a little rich):

The Speedpro Weber/Dellorto book is also excellent.

re: idiots guide - I don't think it's a job idiots can do..... It was considered a 'black art' in the days when lots of folk had DCOEs - - Bob

Idiots guide (tongue in cheek version):

1. Book into a decent rolling road with experience of jetting DCOEs.
2. Take it along and let them tune it properly
3. Give nice man cash
4. Drive away with big smile on face about how much better the car goes.

Virtually impossible to get a decent result by trial and error on the road.

Does this help?

Thanks for the replies so far guys, theres some interesting reading to be done there. Having road tested my `Toy` a little I`m inclined to leave it as is without further fettling. So, I`ve booked the car in at Northampton Motorsport for a proper job to be done. I think it makes sense?!
