I never was impressed with the flow of my 402b sunsun can, and it always sucked a little air, but then the primer button popped and stopped working and it started suckling so much air it stopped a couple times...
After buying a ' penguin 350 to replace it I took it apart to see what had happened. I was expecting to see a broken plastic pin on the primer.
The nut had come loose leaving the primer plunger fully depressed.
Just for the heck of it I installed it on a 10, the flow was crazy!
It's back on my 55 to stay for a while longer.
I'm pretty sure the nut was never fully tightened, you can just push down slightly on the primer bottom and it will decrease the flow a lot., its a flowing now though and not suckling any air at all!
