Poor Starter - Weber Auto Choke Problem?

[CAF]

I have always had a bit of a problem starting my Robin Hood S7, but normally if its with in 7 to 10 days it will start eventually (turns over for ages before firing up), I have a original Ford/Weber 2V post 1985 carburettor (2.0 litre) with automatic choke could this be the problem? If I start the car after 1 or 2 days it only needs half a turn and its going. I live in Dorset and have looked around for a Weber specialist to discuss this with, but have had no luck. I am sure I have read the Weber auto chokes can be a big problem? Any comments and suggestions would be appreciated. Thanks in advance.

My solution would be to fit a weber 32/36 with manual choke, not only does it solve your problem but you'd get a nice power increase too

If you have a mechanical fuel pump fitted, that could be the problem. The fuel in the carbs will evaporate over a few days. It then takes the pump a while to resupply them. If you fit an electric pump this problem should be solved. If you already have an electric pump, then carry on with the head scratching!

Do you have any easy start/ brake cleaner etc. Leave car a few days spray into carb if car starts instantly even for 2 secs then an electronic pump req to solve 

choke don’t care if car left for 2 weeks or 2 months. But it sounds like fuel starvation

If I use Easy Start it will start straight away and keep going, surly if it was fuel starvation it would cut out again almost instantly after firing up? I am almost sure its a mechanical fuel pump, but I will check.

I think it is the fuel pump, as described earlier. The start on easy start will turn the engine over many more times than at cranking speed.
