Help -Spark Plug and fuel oil mixture

[Mike Gustin]

Hi everybody, I am in a position where I cannot check the motor. I do not know the year and I think the HP is 110. In the pic you can see RVO and V4. I need to pick up spark plugs....any idea?
Also what is the fuel/oil mixture? Yes

If the VRO ( Variable rate oiling) system is working OK that is what mixes the oil and gasoline in the correct, variable, ratio .
Until you confirm that the VRO is operating correctly run it on a 50:1 fuel mix

To determine what plugs you need you need to know the HP and year
then you can look up the correct plugs here

To determine the year and HP you need the model number which is hopefully on the ID plate on the port side mounting bracket. then you can look up the HP and year here

Very probably the plugs are Champion QL77JC4, gapped at 0.030"
