Re:Difficult to restart hot AD #1359

[Juraj Lanyi <juro@domain.elided>]

I would like to thank for all your advice. I will do all the checks
suggested although I am afraid of messing with carburretors.


I can definitely remember, that there was gas smell as I was unable to start
the car first time, because I got out of the car.

I checked my plugs recently and the insulator were pretty light,
maybe too light. Can this speak against flooding ?

On the other hand my fuel consumption is about 14 litre in the city (most 10km rides)
that's about 17 US mpg. I am very light with the throttle.
The car runs well although not excellently. This seems too much.

I was told that Alfa 2000's are prone to flooding by my friend. Is this true ?

My 1600 is much different in behaviour.

I will use electronic distributor from my 1600 in this 2000.
The battery is OK. I could also swap plugs.

There was also suggestion that starting device could contribute to too much fuel.

How does it work ? I have choke lever in cabin. The carbs are DellOrto DHLA
and the choke cable is acting upone 2 small levers on the carbs.

It is working pretty weird - on both my cars. Either it has no effect
or I get 2000 to 3000 idle speed.
