Default Golf mk2 is dieseling

For the last month the wifes mk2 golf 91 1.8 seems to have issues with the carb. On startup idle speed instead of 10k rpm shoots up to 25/30k rpm, it does not go back to normal when the engine has warmed up.

Plus the fun one...

when the ignition is switched off the engine will fight with itself for up to 2 minutes afterwards (getting lots of looks from people).

It is intermittent as half the time the problem does not happen.

I was going to start off with finding an airleak, checking rotor arm, dizzy cap etc.

But is this a normal issue?? and thought that it was something to do with the choke betting stuck as it's an intermittent issue? Any advice would be appreciated

Okay have checked rotor, dizzy cap, lubricated throttle cable and the golf is still coming to life after the ignition is switched off.

Here's a video of what happens.

Next I was going to check the timing but anything else I should check for??

"run on" is usually timing or vacuum leaks. but the pierburg carb will do that for you also! air leaks have a massive affect on the carb so check all pipes! then try wiggle the carb around to see if the base adaptors split. my last golf raced away when cold but ticked over fast when warm. i few perished pipes on the n/s was the culprit
