Carb issues

Ok I just got home and after sitting for 4 hours I tried to start it after checking the fuel levels,the rear carb didn't change the front carb was down 1/8" and the center was down 1/4".Which this is consistand with how it did after sitting over night without being started.It turned over about 10 seconds and I stopped,I did pump the gas a couple times to see if it would hit any but it didn't,So I checked the fuel levels to make sure where full was on each one.Went back to start it and it turned slow like it was a little rich and hit but I put it to the floor to try and help it out but the extra pump did caused it to not start.Maybe a new set of plugs will cure it.Odd thing though as I ran it earlier in the garage I was checking temps all around and the fuel line coming out of the pump was 150 deg.But to the touch it wasn't very warm.It got cooler as it got closer to the carb which was 80-90 deg at the carb.The timing chain cover was 150deg also so it was transferring heat into the fuel line.Anyone else check the temps of their engine?I'll switch plugs tomorrow and see how that does.Getting closer.
