Could someone please list the things you have to do to check and mod a Jetex 22 carb to work and perform properly.

1 - Check it doesn't have Jetex written on it
2 - Go to 1

Not the ones I've had. As I say, treated right and not bought from some dodgy ebay seller direct from india and a change of the jets and they've given perfectly good service.

Got to agree with Donnie, the jetex i run goes well even without changing the jets, you say jetex are crap, have a look on carb set ups on this forum to see who's having the most problems after they have binned the jetex, seems to me it's just luck with any carb.

haven't owned one myself but problems i have come accross only relate to poor quality control
check float operates freely ( remove flash from body and float )
float needle damaged on almost new carb
jets and atomisers aren't always the same size or machined the same, although marked the same
