Default 32/36 DGAV idle mixture screw

I’ve got an issue with my escort where it was fine, and now suddenly won’t idle once warmed up. It starts fine, idles on choke but once up to temp and choke cuts out it will run when revs are kept up to it, but if you lit it drop to idle it stalls out.

I’ve been doing some research and a two main things have come up as possible auses.

- vacuum leak
- blocked idle jet

I’m not sure it’s a vacuum leak, at least not around the carb gaskets at a spray over the carb when running didn’t cause a surge. So I’m was leaning towards an issue with the idle jet.

I was looking over the carb before pulling it off to send away for a service, and noticed something funny with the idle mixture screw. Every picture/diagram I’ve seen shows the screw and spring projecting from the housing. But on my carb, the screw looks to be buried deep within the housing.

Here is a pic of the idle mixture screw location on my carb.



It doesn’t seem like this would cause a sudden inability to idle, but it’s not right is it?
