Gotta get this sorted out!

After trying multiple rod and jet combinations on both the 600cfm and the 800cfm I have a hard time believing it was both carbs. Actually these are not the same plugs. I started with FR5's , then tried FR4's by mistake, and the new ones are a 6 heat range.
I snapped some pics of the FR4's when I took them out but still can't dump enough data off my phone to get enough memory to upload them.
I wanted to wait to install the carb but I got pressed for time to get it back on the road.
Sorry for not having a definitive answer for you guys, but I really appreciate all the help.
