4-cycle
Briggs and Stratton made almost exclusively four stroke engines. There is no fuel oil mixture for a four stroke engine. Are you sure you have a two stroke engine by Briggs and Stratto? rhg
The fuel system on a Briggs and Stratton engine works by fuel being gravity feed from the fuel tank. Fuel goes to the carburetor where air and gas the mix, after the air and fuel mix it is feed into the engine where the engine goes through the four strokes.
There is no "gas oil ratio", the 3.5 hp Briggs and Stratton engine is a four-stroke design, oil should NOT be put into the fuel!!!
If the engine is four-cycle, the valve seals may be worn, causing a small amount of oil to seep into the piston cylinder or combustion chamber. If it is two-cycle, the oil/fuel mix may have a little too much oil.
20 oz. if fully drained, 16 oz. will usually be used in an oil change.
There no positive way, but you can get an idea from the Model number. It will be five or six digits. The last four describe carb, bearings, starter, etc. The first one or two are the cubic inches of the engine. Current decals are a torque ratings. You can also go to Briggs at the attached link with the model number and see.
The best way to know if an engine is 2-stroke or 4-stroke, is to look for an oil spout. If the engine has an oil spout where oil has to be poured into, it is a 4-stroke. If the engine has no oil spout and the oil has to be added to the fuel, then it is a 2-stroke.

The Ottoman Cycle
The Briggs & Stratton engine company founded in 1908 owns and makes Simplicity snow blowers. These blowers include the four-cycle single-stage snow blower, the dual-stage snow blower, the large-frame dual-stage snow blower, and the Simplicity Signature Pro Commercial Duty dual-stage snow blower.
A car engine is a four cycle internal combustion engine, there are four cycles. 1. inlet cycle 2. compression cycle 3. ignition cycle 4. exhaust cycle hope this helps
NO, not as lubrication in the crankcase.
