Thanks DD,
Yes, all stock components. Do you know what the GX set presures are?
The two sets i have have been taken from other makes of engine so i dont have a referance.

I have mesured them and a standard A12 set:

Standard- 25lb seat and 100lb over the nose (checked at 9mm lift)
Set 1 - 40lb seat and 150lb over the nose
Set 2 - 100lb seat and 230lb over the nose

I would need to know where the GX set fit in comparison.
