Trouble shooting my edelbrock performer carb please

I'm going to check the choke tomorrow but i'm pretty sure the springs rods and jets are all stock. I spoke to another member on here who was very helpful and informed me that since i have a cam with lower vac i may have a problem with the springs not keeping the rods down and i may have to go with weaker or shorter springs. also i have to get my dial back timing light and double check my timing tomorrow as well
