Hi Rod,
Sorry it's been so long getting back to you - how time flies when you're having fun. The engine has now been tuned (with the flow meter I bought from you) and actually required very little adjustment. The Beetle's body is in Melbourne getting painted so am looking forward to putting everything back together soon.
Whilst my car is not the high-end project you're probably best known for, the advice and assistance you provided was outstanding. It's unusual to find an internet site where you can actually talk to an expert and get the right bits for your engine and transmission, as well as plenty of good advice to go with them.
I've attached a photo of the engine end of the chassis - it's not super flash but I'm happy!
Cheers, Roger
