Twin 40 1.3 jet sizes

[Mikey070890]

Hi.
iv just fitted some twin 40s to my 1.3sr they’ve come off a 1.4 nova. It starts up and idles fine. Would the jets be ok to use on my 1.3 if they’ve come off a 1.4?

thanks

Possibly a little too big - you may only need to change a couple of the jets e.g. main and idle. Read this for the preferred setup:

Also worth checking the chokes - I have 30mm in mine and perhaps a little too big so probably swap back to 28mm.
