Electric motor to gas engine conversion

[Dirn]

I have a 7.5hp elec motor and need to convert it to a gas engine... I know they rate the two differently but I can't remember the conversion or ratio.
Does anyone know the proper conversion? Or have a link?

Thanks!

Never mind, rule of thumb is 1.5x the hp of an electric motor. At least in my application.
