i believe the difference is w9 is 601 thread …….do the regular ones not work with the sr71? what is the difference between the one on w9tech and dhgate
most online retailers sell 510 thread -- so u would need an adapter to use ?
hmmmm -- I'm having my 1st learning curve with the sr 74 ---
I been getting great vapor -- all seemed good -- then I opened up to take a peak and noticed oil in the bottom chamber right below the glass rod ?? I feel all is tightened proper ?
ill have 2 do a full wash again tmro and see if something just isn't right -- but I think all is fine --- I will admit I didn't tighten crazy -- just cause -- but its tight enough imo
oil below ? any experts ? much respect
