As mentioned, check the cam on the end of the lever.The lift works fine in auto play. The arm lifts when I use the cue lever, but descends if I let go of the lever. Won't stay up.
You’re probably on to the source of the problem.It takes some amount of resistance from the cue arm mechanism pushing against the cue lever cam to keep it stuck in place. I’ve found if the arm cue height adjustment is set too low there can be too little pressure against the cam and the spring will overcome it, flicking the cue lever back.
Ok. Looked at the SM where it shows lube points. At the lift lever is shows to use Wacker Silicon oil AK 500K. So it should have dampening fluid? Where exactly should it be applied?
I thought about doing that, but was afraid I might crack the plastic cam. As I said, the SM shows #6 triangle pointing at the lift lever cam, Says 500K silicone used. I had some 300K and tried it. Did not help.Notice on my 1218 how the cueing lever is slightly bent inward. I recently completed refurbishing the unit and set the lever straight. It would not stay engaged/forward until I tweaked it back. Through some reading I found several other owners have the lever slightly bent as well.
I read a suggestion where sanding the metal lever perpendicular to the plastic cam as well as cleaning the cam of grease can correct the condition. I'm pretty certain that the cueing lift system is the same on 1218 & 1229 decks. Please report back if you get the issue sorted, I will as well.

Well, The auto play & lift work as they should. Considering these are 50 yrs old. I guess it's OCD raising it's ugly head.
Nice looking decks. I do have a fully functional 1249.Totally get that, I'll still be looking in to the issue. I'm pretty new to the service aspect of this hobby, just collecting stuff for 20 years and didn't do anything until recently. These Dual units really try one's patience. Once I would get things 90% right, I'd get all OCD to attain 100% and regress. I think I did every procedure 5 times over a month on the 1218. Scored a 1215 for $20 and only did everything twice over a week ! Have both working well and have dedicated the 1215 as my 45 stacking deck. I'll keep you all posted !
