Hi
Glad my support helped. but the valve is NOT part of the BMQQ-2 parts assembly and looking at all BMQQ-1 also there is no valve, I have never heard of the BM-QQ having its inlet air intake restricted this can cause all manner of issues.
So I contacted BM, and no a valve has never been part of the kit, what they think has happened is that a worker left the maxi jet venturi valve that comes with all maxijet pumps in the kit by mistake. I have checked all 23 units here and not one has this valve, so please do not use it. It is not mentioned in the kit list either.
I am glad you are getting it dialed in
