So my engine started having 4 beeps every couple minutes. Oil resivoir was full. I jumped the two wires and beeping quit. Bought new oil reservoir and replaced it. Beeping resumed as before. So I replaced the gas filter. Emptied old one in a bowl. No water. Pulled lower screw below gas inlet and let drain in case water was in there. No change. Motor runs fine with no beeping with oil resivoir jumped. Beeps when it’s not and after a few minutes goes to a full beeping tone if rpm’s are above 12k. Oil resivior is completely full….like no air gap. Have vented it multiple times on old and new one.
What can I try next?
