G2 have starting issues

[rsviper94]

I am working on a G2 and it is starting to drive me crazy. I had it running ok the other day but now when I step on the pedal the motor turns over but it takes forever to start but once it starts it runs great as long as I keep the rpms high if I stop it takes a while to start again. I have installed a new TCI, coil and carb before this new problem started. The battery is testing at 12.6 volts when not running and testing at 13.7 volts when running at high rpm. The strange thing is that the red/white wire at the coil is only testing 10.7 volts when I am trying to start it. It seems to have a harder time starting when the motor is hot. Any ideas??????
