T5 172 reed valve 30mm Delly starting point !

Mate had this built by Chequered past but the carb just seems to be as it was out of the box - it was actually the wrong 30mm for a Vespa but luckily I'd one on my GP for a swap.

Anyway, I was just looking a starting point for slide, needle, atomiser and main, it's a 55 idle in it which should be close. As the title, it's a 172, didn't have a good look at the manifold, not MB though, he's running a PM pipe.

Any help appreciated.

Cheers

John

1st thing he needs to do is get rid of the pipe

Yeah? What do you recommend mate? He'll be gutted, nice shiny new chrome PM :oops:

And also any recommendations on the jetting?
