Its too short!

[Bone]

Just got a Straight shot nelson spring kit to put in a black magic autococker and the valve springs (all four of em) seem to be substantially shorter than the stock one. I know the idea is to lighten the valve spring but im not even sure these things actually manage to close the valve!

It even seems to rattle when the valve is back in place....

I have seen this spring kit suggested for use with other valves (namely the 3:16 Rat valve)..... does it have a larger valve body or summat?

cant bring myself to put the gun back together with a rattling spring coz it's just gonna hiss at me.

Are these the right valve springs?

Maybe they were ment for the rex kit cause if memory serves me right, when you install the rex kit the bit at the back which alows to to change to velocity is twice the lengh of the brass stock one.

aha! could be, could be! guess what i've got sitting next to the little baggy with the springs in...... a little baggy with the rex kit in it! need a pillar drill to do that one though....

 

[Hudson']

pillar drill to get the rex in????

 

[Mark]

He doesn't have the adjusting hole for the rex drilled in the back block and depending on which beaver tail he has fitted that needs a slot cut in it. No point in fitting a rex if you can't adjust it

zigactly!

ah, well with my cocker i never drilled a hole in the back block, you simply hold the back block back/hold your finger on the trigger then you have enough space to adjust it.

...theres an idea.... no need to wait then! In goes the Rex kit! The hole can be drilled later if at all!

cheers for that Com!

You got a very old spring kit. Between 98 and now the valve chamber has been getting deeper and deeper. The springs you have are for a pre-98 body, and Nelson style pump guns.
Take them back, and make them give you the correct set.

Doh! Thought it might be something like that but hoped it wasn't....... ah well! Thanks Van, at least now i know!
