I haven't played with my sential in 5 years because it breaks balls every game.

I have just learned that it's because of bad blow back and a new valve pin will fix this from a topic 4 years ago.

Where do I get a new valve pin? If I still can?

Action Bob, aka Crash STP, aka Evil Action Bob, may have some still. I bout a few AM parts from him last year.

Hey Fry, how's my ole bud doing?
So you really think Action still has some more of the better valve stems?
I was thinking of maybe shoertening mine down the width of a dime, LOL. That seems to be the standard denominator.

[Fryloc]

He did at PPIII.

CHecking my stock will let you know if I have new or old style valve stems. Either way the new lenght ones will be available soon. Have surface grinder will shorten.

It would be more interesting to know if shorter is better. I'm not sure you can get a Spyder (clone or not) valve stem longer then then what came with the Senti?

[splattttttt]

I just ground off 3mm off the valve stem, and there now zero blowby the feed port.
Tested with my Ricochet 2k. Went through an entire fill with out any problems.
One problem I havent noticed till now since when I had my D-ITS, was a significant amount of roll back in the breech. Remember I solved that issue with an o-ring that I glued to the cupped part of the bolt. That totally solved the issue I found when trying to achieve the best level of centering ball in the breech and retaining the BIP (ball in place).
Other then that, I could use better bolt o-rings, but even though the ones I have in there suck, I still didn't notice any blowby.
We're good on this now. This change now makes the Senti the best mech blowback semi I ever played with.
Let's go to town.
