Last time out we idled back in and motor ran perfect i should have ran it at higher rpms i now know for sometime before bringing it in. Once home i went to flush motor and it started missing and idling up on it"s own so i thought must have fouled plugs. Installed new plugs and did index them. Motor runs the same as it did with old plugs so i pulled plastic housing from intakes and it is full of fuel.Started motor back up and fuel runs from lower intakes and when i shut it down it just poured out. Any ideas ? Any comments would be greatly appreciated thanks
