Mk2 Concentric
« on: 03.03. 2025 22:27 »
Hi all

Has anybody tried fitting a Mk2 concentric (or two for that matter) to an A10?

I fitted a couple to my SR and it started easily and ran ok on acceleration but messed about at other times. I did not have the time to change jets and mess around with it so put my Mk1's back on but I am curious as to what jets, slide etc. others may have tried in the past.

My apologies to the concourse brigade :)
