mate when @Th3_Huntsman and i did Kit she was rough as guts trying to start and picked up alot of revs when he sprayed WD40... but you and I both agreed there would be issues with air leaks..
Well the good news is that it is clearly pulling air in, at 22 seconds it is very clear, and regardless of whether or not it is the main issue, you will have to put those gremlins to bed first.
Hmmm, missed the video yesterday boss, I would say the exact reason for the pilot screws being that far out is for the leaks, check the clamps are all perfectly circular as well, I have some spares but I think they are leaky
Whip em off for a closer look, I think @ruckusman has a bush mechanic fix for boots using big heatshrink as well... Or $120 from millway spares will get you 4x brand new balius ones
Also how is your fuel flow? I would thought continual cranking like that would likely flood it? Possibly check your vacuum hoses as well and fuel tap with to old suck test and prime. mate.
