Thanks for this video. It's hard to find advice on Dellortos. I've watched this quite a few times already! What fuel pressure pressure do you run? I can't read the gauge!

New subscriber here love your content 🎉🎉 is that the huco ignition coil? I'm two minded on getting me one, some say it's bad some say it's good I don't know. Just looking for a good coil for my mk1 golf. Love from Cape Town, South Africa!!

I was wondering what fuel pressure you use. Then I read the comments in the other video. 3-4psi. Next question: re a base setting on start-up for the idle mix screws: I've read everything from 1.5 to 3.5 turns out as the starting point. I've got a 1972 GT 1600 Junior with a 1750 engine.

If only it was that simple, try as i might i cant get my carbs to balance, i get one spot on and the other one is way off and vise a versa

I use mercury vacuum sticks, far superior to this.
