All perfect, works exactly as it should, absolutely stoked, been one of the biggest bugbears with these carbs after the cam modifications. With this solved I think these carbs could go on forever, nothing to wear out or fail now. Big problem is I only ordered one needle and seat to try so now I have to wait another month for a supply to arrive. Now I have it sussed out it is fairly simple to do for me. I have at least 20 useless Victa needles here if anybody wants them :D, I will never be bothering with them again. Such a good feeling to be able to turn the tap on, give it a prime and just pull it and not constantly fear the needle was going to either flood or stick. I worked out how to remove the seat so no problem there, thats easy, run the drill down through where the seat was and push in the new Briggs seat, probably a couple of minutes,and turning the needle down is no big deal. Super super happy
