Ok so I ended up doing the reverse. I put in a lighter valve spring and kept the stock main spring.
Now the valve spring is actually so light when the gun is not gassed up, the main spring has enough force to fully open the valve. But gassed up, event at 150 psi it work just fine and doesn't fart...
I initially tried lighting valve and main spring, farted. Then I tried stock valve spring with light main spring, faster. But light valve spring and stiff main spring doesn't fart.... I haven't seen anyone mention that they use this combination. But it seems to work.
