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
T5 172 reed valve 30mm Delly starting point !
Yeah? What do you recommend mate? He'll be gutted, nice shiny new chrome PM
And also any recommendations on the jetting?
