Happy but Sad Day

[MN Rooky]

I couldn't take it anymore. I have been working on my truck for about 3 years now and I'm putting on the final items. I have to get out of the shop and see what it looks like outside. I fired it up and pulled it out. First I stopped to admire it for a while and take some pictures. Then the temptation to drive it a little more got to me so I took it around the in the field. When I came to the driveway I tried to give it some gas and move it into 3rd. This is where I became SAD. The carb flooded out from what I can tell. The truck ran when I started working on it. The PO said that the carb needed to be adjusted. I cleaned a crap load of rust out of it and replaced the everything from the tank to the carb. (Edelbrock). I have been reading that I may need a fuel regulator. Is there a good way to check your fuel pressure?
