I have a HIF44 on a 1380. I rebuilt the HIF44 with the full rebuild kit from SU (Burlem Industries)
Always consistent. 7 turns to start cold. One turn to start hot.

It could indeed be a vacuum leak somewhere. What are the common places where the leak could be and what is the easiest way to find it?
Should I test cold starting with the vacuum advance disconnected?

I have tried with the dizzy vacuum line disconnected but this does not give result I hoped-for.
I have connected a vacuum gauge which indicates between 17 and 19 inches but the needle does vibrate quite a bit. But if I turn the mixture richer the needle stops vibrating and remains nice and steady but then the engine is too rich.
As far as I can find, the vibrating needle means that the valve guides are too loose. I don't know if difficult starting and fluctuating idle are symptoms of this. And how would making the engine richer remedy this?
The car doesn't use a drop of oil either.
(Here is a video of the vacuum gauge, but the needle vibrates so fast that the video frame rate does not keep up. So imagine that the needle vibrates… https://youtube.com/...w?feature=share)

The idle problem has always been there. Possibly the previous owner also tried to solve it with the mixture.
