Default RE: How much oil do i need?

ORIGINAL: grant-RCU

I am getting a ST 90 converted to ch igninton and a gas carb. The crank and rod are stock. The TT 120 on this http://tech.flygsw.org/ttpro120conversion.htm page is running on 16:1 ratio which is 8 ounces to 1 gallon of gas. Does anyone know who did this conversion.

Is this enough oil for a gas conversion with stock bushed rod ends?

Plenty of oil, 6.5oz/gallon would bring you into closer to 20:1 which I think is ideal.
