edinmass 11,246 Posted November 14, 2020 Share Posted November 14, 2020 My limited knowledge of them indicates they are early, off small engines and motorcycles for the most part, and some of them are unbelievably expensive. Is it a motorcycle part? Link to post Share on other sites
Simon Anderson 10 Posted November 14, 2020 Author Share Posted November 14, 2020 I am unsure what’s it off i have looked through a number of books and internet with very little information. the throat size is 1”1/8. Link to post Share on other sites
Simon Anderson 10 Posted November 23, 2020 Author Share Posted November 23, 2020 It may appear little is known of this carburettor. Link to post Share on other sites

Simon Anderson 10 Posted November 24, 2020 Author Share Posted November 24, 2020 Thank you Benoit, this help me regarding how they set up the spring rate on the air valve. thanks again Link to post Share on other sites
Benoit 54 Posted November 24, 2020 Share Posted November 24, 2020 Here's one I bought off a guy on the Tour de Fleurieu a few years back. I might try it on my Le Zèbre some day. Link to post Share on other sites
Simon Anderson 10 Posted November 25, 2020 Author Share Posted November 25, 2020 That is a fantastic looking unit. I would be very interested in what springs it uses in the air valve. As mine has none, and from reading the info you supplied there was two springs. Link to post Share on other sites
Benoit 54 Posted November 25, 2020 Share Posted November 25, 2020 I'm not sure if the spring is original. It looks a bit home made. You might find someone else with one of these on the SmokStak Downunder forum. Link to post Share on other sites
Simon Anderson 10 Posted November 25, 2020 Author Share Posted November 25, 2020 Thank you Benoit, I appreciate you taking photos for me. Yes it appears to be a home made spring, but it could be the correct one, who know. I will check out the other forum. Link to post Share on other sites
