Do you have a Chevy, Ford, Cummins, Briggs, Jacobson, Kohler or Wisconsin Robin engine? Also engine numbers would help. Due to COVID most of the techs on this site have lost the use of their ESP so we need you to provide us with a better picture of what you are talking about.
I guess I’ll have to do it the hard way by back tracking through the mower number. Sure would be easier if I had engine numbers. On top of that, it must be a tractor.
More than likely a Ryobi model 7T90HU engine. No good pictures or diagrams to be found. Don’t have one around to take a look at, plus don’t know if the OP means oil fill cap or oil drain cap. He’s going to have to take a couple of pic and a better explanation of what he needs. Already spent too much time on this one, but now I’ve got to figure it out.
