For the aluminum the intake valve clearance is .005 to .007 inches.
exhaust valve clearance is .007 to .009 inches.
Cast iron is - intake valve is .007 to .009. inches
exhaust valve is .017 to .019 inches
On a valve-in-block 8HP with an RJ19LM or equivalent plug, it is 0.030"
Briggs straitton
It is around a 5 hp. *this is incorrect: the ones they sell currently would be more in the 7.5-8hp range, seeing as an equally featured 190cc briggs and stratton engine is 6.75hp on a lawn mower the additional 15cc bump it up to around 8hp.
Capacity is 36 ounces. I highly recommend you use Synthetic oil in this air cooled engine. Change it once each year.
For an 8hp Briggs & Stratton engine, it is recommended to use SAE 30 weight oil for warmer temperatures and 5W-30 for colder conditions. Always check the owner’s manual for specific oil recommendations, as some models may have unique requirements. Ensure the oil meets the API service classification for small engines. Regular oil changes will help maintain engine performance and longevity.
318cc. is 8hp. 305cc.is probably between a 6 to an 8hp.
A Briggs & Stratton 8 HP engine typically requires about 20 ounces (or 0.6 liters) of oil. It's important to check the owner's manual for the specific engine model for the correct oil capacity and type, as variations can exist. Always ensure the engine is level when checking or adding oil to maintain accurate readings.
There are two types, both on the camshaft. Lower HP (around 8HP or less) typically have a lobe with a bump on it that keeps a valve (often the exhaust) open at RPMS under 250, aiding in starting because the valve does not fully close) Larger engines have a counterweight on the cam that swings "up" at the same RPMs are "removes" the high spot achieving the same affect as above.
For an 8 HP Briggs & Stratton engine, the oil capacity is typically around 20 ounces (0.6 liters) or 0.5 quarts. However, it's essential to check the owner's manual for your specific model, as capacities can vary slightly. When adding oil, ensure the engine is on a level surface and check the dipstick to avoid overfilling.
For an 8hp engine, the specific spark plug required can vary depending on the manufacturer and model of the engine. Common spark plugs used in small engines, including 8hp models, are often designated as types like NGK BPR6ES or Champion RJ19LM. Always refer to the engine's manual or specifications for the exact spark plug model recommended for optimal performance.
Depends on the engine. Generally between a pint and a quart. A Briggs and Straton 8hp takes about 24oz. Kohler or TecumsehPower should be close to that as well. If you are changing the oil and the engine has a dipstick, I would put in a pint (16oz) and then check the stick. If it is still low, I would add about 2oz at a time and check again until it does read full. If it is older and does not have a dipstick, just fill it until the oil comes right to the mouth of the fill opening.
Not very fast, possibly about 25 mph.
