I'm looking for some advice on the fuel mixture I should be using. I have an XTV-27003A and in the manual it says to use "1/4 pint of Wards Riverside Outboard Motor Oil (or it's equivalent) of SAE 30 or 40 viscosity to one gallon of gasoline. Do not use D.M. or D.S. rated oils."

So I guess my question is this, it there an equivalent available today? Should I use 2-cycle marine oil or chainsaw 2-cycle oil (it seems like I've read both somewhere) and what is the proper mix?

I finally got this to start today after a lot of cleaning and other aggravations. Now it starts great but will only run for 10-20 seconds before stalling. Currently, I'm using a marine grade oil mixed at 25:1. It seems like I remember reading that for these old motors that's a good mix. Any help would be greatly appreciated.

That is a Clinton J350 5.76 cu. in. it uses 16:1 fuel mix.Use Chain saw 2 stroke oil. Or that which is appropriate for Air cooled 2 stroke motors.
Don't skimp on the oil.These motors use plain bearings.

Not likely, Fuel mix doesn't affect operation except in the extremes.
More than likely you will need to clean the fuel system if fresh gas and oil doesn't help.And adjusting the carb isn't effective.
