Russ, thanks for the tip!

Coincidentally, I bought that book fairly recently but haven't really got round to looking at it properly. That's a good reason for taking it off the shelf!

Cheers

I'd recommend getting yourself a copy of "the Vintage motorcyclists workshop" by the excellent Frank Farrington AKA Radco.....if I remember correctly there's an Binks, AMAL and AMAC jet size equivalent chart in there I think a 40 AMAC is an AMAL 160......plus there are a myriad of useful snippets and techniques for faffing with Vintage motorcycles

Thanks Russ, appreciate that. I'll give that a try for starters.

seems a bit light you'd probably want to up that to a 40

Hi all,

If using an Amac 15PJY carb on a model 9 (1927), just wondering if anyone can advise what jet size I should be using please...or at least starting off with? I have a carb with a size 30 fitted, does that seem about right?

Thanks,
Steve
