Well guys, the AT&SF fired up again the other day and ran for a few seconds longer and this time included a blip of the throttle.
Sorry I can't post it here, you can only see it on Facebook, unless anyone knows how to change it to a format that can be seen here.
They are still having issues with it running very fat, but there are things coming in the post (mail) to rectify the problem, smaller injector nozzles maybe, they didn't say.
