Hopefully, others will post with information on how leaning the low speed needle helps them.
On one of my GMS .32's it helped, the other one it didn't help:-(
Some people may still need to drill out the brass insert to improve fuel delivery - there are some of the brass inserts way out of position and off center when they come from the factory, this causes fuel starvation. Drilling the brass insert improves fuel delivery dramatically on these units.

I have (2) GMS .32's on a
Hobbico TwinStar {just a weee bit overpowered}
One improved with adjusting the LSI, while that did nothing on the other.
I drilled out the muffler pressure taps slightly larger, and put Hobbico muffler extensions on both engines.
Tried different brands of fuel & percentages of nitro, and different glow plugs.
At WOT/horizontal both run fine, but vertical & one dies while the other keeps on keeping on.
Would drilling out that brass insert help on mine,
with remote needle valves?
