Ok, so I just got an RX8 and was told it's flooded. Kid ran it out of gas, put gas in it and didnt cycle the fuel pump. Also says the motor had good compresson. So I'm trying to deflood it after awhile of trying I start to let off the gas slowly and see if it'll try to start, but I have the gas almost all the way up and it'll backfire pretty bad and won't attempt to start. Bad compression or just very flooded?
