Tried 2 things today:
Richening the mixture screws by (about) 5mm exactly on each side
Lower the clip on the needle from 2 to 1.5
Once it was all back together, idle was a bit weird so I thought whatever...got about 10m down the road and realized there was some big hesitation as soon as it got to 6k (or anywhere in the midrange). To lean !
Well, it's progress...2 was ok but felt a bit, so, hopefully 2.5 should fix that.
Extended bung for the wideband should be here in 2 sleeps
cheers guys
