I no longer work on 250’s but I recall one every so often that would do the slip off thing, I would usually switch the lever but never noted which I used since it so rarely happened.
Scubapro G250 can't be serviced??

I wonder if it was because those particular levers were bent in some way? I must've converted more than 30 or so and have never experienced this...
It was probably my assumption at the time, never liked the curly feet levers for this, I’ve memory serves they made lever height hard to set but I could be wrong??

I get more consistent results, tuning wise, using the non curly feet levers on converted G250s.

This old thread looks to be relevant.

Scubapro Second Stage Lever Height
OK, I think it’s time to do a little review of how the 109/Balanced Adjustable/and G2xx series second stages differ from other demand valve regulators. The first clue is that they all have Single Adjustment Valves. The Diver Inhalation Adjustment Knob notwithstanding, outside of replacing the...

Scubapro G250 poppet assemby
Hello: I am working on a very old Scubapro G250. It has the older poppet assembly with the large seat, blue assembly, and metal extension with single oring. Does anyone know if I can simply replace this entire poppet assembly with the newer all plastic white assembly. For those of you who...
I only had one curly feet lever and found the legs would stay bent out once snapped over the barrel and were hard to bend back into correct position so the lever was too loose. I found the old levers stiffer and they would always spring back to original position once popped onto the barrel without issues. It’s only 1 curly foot lever but I didn’t bother trying to get more since the old ones work great seemingly.

I recently converted 6 G250s in total over the past 2 weeks. 4 using old levers and two using .141 curly feet levers. I had tuning trouble with only one and it was curly feet one. Cracking was higher using curly feet lever. Easier to get lower, see posted photo above, with original levers IME.
I don’t remember if there is a bulletin. I do remember being told to replace the components during a service clinic several years ago. It was also covered again in an update clinic I just took.
