If I might ask where did you get your Alamo City hammer? I'm trying to find one, I emailed them with the contact info from a cached page of their website but have gotten no response.

Edit: got the contact info for someone at alamo city from another thread. Pm me if anybody needs/wants it.

the problem is the lighter hammer is not striking the Valve hard enough now to fully re-cock.
Two options -
1. Lower input pressure further to reduce pressure on the valve ... this will work to a point as you'll end up running into flow issues which will require further mods to the valve and internals.
2. Increase spring pressure with a harder spring (from spring kit). again this is diminishing returns as more spring pressure will eventually cause further re-cocking issues.

The best option ... reduce valve pressure with lighter valve spring (buy a spring kit) and reduced input pressure to ~300psi, start with the lightest valve spring and a stock mainspring. Drill V/A for more flow (~3/16" diameter from VA to LPC and from LPC to Valve).
Start chrono'ing and tuning with the spring kit as you go. A 300-350psi spyder is not uncommon with the right mods. It just takes the time to properly tune the marker after mods ... there is no real bolt and go here, especially when you added so many parts at once.
