PROSPORT SPRING GRIEF!
Posted: Mon Jun 06, 2016 10:44 am
I have two Prosports both short stroked with tbt piston extensions 25mm HW seals and Titan XS no.10 springs.
They were both set up shooting nicely at 11.5 and have been fine for the last 4 months.
Now both of them have lost power dropping to 9ftlbs! Iv stripped them and the only thing i can find thats causing the drop,
is the Titans,which were new on fitting have lost nearly 10mm in length.
On fitting they were 232mm now they are 225mm.
Im assuming this is my power loss!
Iv tried adding preload but the springs become coil bound before any improvement is reached.
Iv always thought Titans were good springs?
Any ideas as to why this has happened? Both guns are running standard transfer ports.
Can anyone recomend a alternative spring i could try? Or any reason why two Titans should lose length so quickly?
Many thanks
