I think after reading all the info on here
I think i have an early v1 mech mayhem. Spyder thread
It cycles but no velocity.
poppit only has 1 oring. The one that contacts the bolt.
What size would the back one be.
In the manual it shows what looks to be a giant oring not numbered next to the main spring. Do i need one ?
It has what looks to be a small metal sleeve on the bolt. ?
And lastly ( for now) the body seperates slightly after airing up. See pics
I moved to left feed thinking maybe the screw set was loose or something on the centerfeed.
