EDIT: The valve lets air through but very little, it's like air going through a coffee straw, is this normal?

I don't think the solenoid mod is meant to put the switch in the compressor nozzle. I think the mod is just supposed to bypass alot of useless internal space. Maybe giving better airflow?

I'm not exactly sure what the mod does, ask at the Spudtech forums if you would like to know. Spudtech sells these modified valves for over $40, I'm sure they work just great. I don't think they're worth that much though.
My friend has used a modified valve he bought from them and from what I know, it fires when you press the button. That article recommends to get that valve from McMaster, and I've used them before, they're good, just a little pricey sometimes. I'd just follow the instructions.

Yeah in the instructions it says not to use that manual bleed constantly because it is only meant for troubleshooting and testing the valve.
I have also heard bad things about repeatedly using the manual bleed, eventually it possibly will break the valve (this is only what I have heard however).
Anyways thanks for all the help

How It Works:
In a soleniod valve there are three places for air. The tank, the barrel, and the air that is going to be released into the atmosphere. Some of the air in the tank will leak through a calibrated leek into the air that is going to be released. When the pressure is dropped from the the pressure to be released, the air in the tank is putting force on the seal of the diaphram, trying to exit through the opening. when the seal is broken the air will be released into the barrel.

I tried blowing through mine today and discovered that air goes right through it. I made the trip to Home Depot and picked out several similar valves of different brands. I blew through them all and discovered that none of them let air through except (ironically) the same model as the one I had bought a year ago (Toro in-line). Rainbird and Lawn Geenie both worked fine. I chose another Toro from the rack and it didn't let air through, so I exchanged my old one. I took it home and hooked it onto my tank and it works fine, only problem being it has male threads instead of female. On the other hand, it is very small compared to the other brands.
