Hi Guys
Am in the process of fitting up a set of 40 dellortos to a A15 with a bit of head work and an upgraded cam and am looking for some jet sizes to get me started.
Any other pitfalls to look for ?
Thanks
Bob

Yes, I hope you have better luck than me finding chokes and jets for smaller engines.Here on my side there are no chokes or jets that will work anything from A15 downwards.

for out and out power:
chokes: 34
mains: 140
emulsion tubes: 7772.7
air correctors: 180
idles: 45/7850.2
pump jets: 35/40
auxilery venturis: 7848.3

for a bit more driveability:
chokes: 32
mains: 130
emulsion tubes: same
air correctors: same
idles: same
pump jets: same
auxilery venturis: same

this is using some program that some1 found here a while ago.

type "jetting.exe" into google or our search bar to see what comes up.
