Response to i want to know

squeezing it into his modded tiny valve , in order to reduce volume and increase pressure.therefore , he is getting good power from 1 stroke..thats just the basics, then theres the barrel length, transfer port, spring tensions.,hammer wieght , pumping linkage configuration , altitude, temperature , and other variables./just read, it takes years to learn all this crap , matter of fact you never learn it all.heres a good way to be forced to learn !
