I'm using the manual fuel pump. G63b 2.0 motor. It took several minutes before it started today. It had been sitting for more than 7 days. I pumped the gas while cranking and then held it down. Neither seemed to help, I just got dry cranking. It took a while for gas to get back up to the carb. I'm guessing it evaporated or drained back to the tank. But I would have thought having the regulator on it would trap some gas in front of it that would let it start and get going.

Is there anything I can do without having to add the electric pump?
