Can everyone help with correct jets size for 1100 engine?
And maybe know where to buy it?
Thanks friend's

From memory the jets were originally 91 (0.91mm). But that doesn't matter as fuel has changed and something around 97 or 97 would work a lot better with modern fuels. I'm looking for one too. There are a lot of jets on eBay but I'll need to remove a jet to check size and shape before ordering one as the descriptions are poor.
