john stones 1 - Moderator Posted July 17, 2021 Share Posted July 17, 2021 Where do you buy the tiny O rings from ? Those on main needles and slow running needles ? What size would they be usually ? Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted July 17, 2021 Share Posted July 17, 2021 Irvine Engines do/did O ring kits for their carbs. I did spend a bit of time on line looking for alternatives for SC/ASP as they seem to be of variable quality but didn't really get very far - the main needle valve ones seem to be a rather unusual sized square section one not stocked by any of the firms I checked. I wonder if Jon Harper might be able to help? 1 Quote Link to comment Share on other sites More sharing options...
