on the starterbox, if i off throttle and on throttle before it dies off, it'll bog.
however if i off throttle and immediately on throttle, it'll be fine!
track testing found similar issues, parts of the track where i got to off throttle for 2s or more; it'll bog when i on throttle back.
my LSN too rich?
If it bogs with smoke it is rich, except if you are way too rich then it will just spill some oil and die before it can burn everything in the case. I don't think I've ever seen a lean LSN die after a short time, so I think you are safe to go in at least half a turn because small steps are not going to be enough.
