TM 5-4240-501-14&P THEORIES OF OPERATION"Easy Spin Starting" "EASY SPIN" STARTING Good compression is necessary in order to obtain the full horsepower of the engine but at the same time this makes it more difficult to turn the engine over fast enough to start it. The resistance of compression is most noticeable during the first few revolutions after which the momentum of the flywheel and crankshaft help until firing starts in the cylinder. In order to reduce this resistance during starting time, various types of compression releases have been used. However, none proved entirely satisfactory until Briggs & Stratton developed the "Easy Spin" starting system. This is so simple one wonders why it was never thought of before. The intake lobe on the cam gear is ground with a small ramp which holds the intake valve open 1/100 of an inch for a tiny fraction of the compression stroke. At slow starting speed the interval of time that the valve is open is relatively long and therefore enough air escapes to noticeable reduce the compression. However, at operating speeds the interval of time is so short that there is practically no escape and therefore horsepower is unimpaired. Actually at 3600 RPM the valve is opened for a mere 1/200 of a second. In all other respects the valves operate as in any other four stroke cycle engine. The force required to start an engine is reduced by 50% with "Easy Spin" and would be noticed most by a person who has difficulty starting the ordinary engine. One thing we must remember. When testing the compression of "Easy Spin" engine one must spin the flywheel "backward", in the opposite direction to normal rotation. This will bring the compression stroke on the opposite side of the cam lobe and allow you to feel the compression. 18 14
What else can I help you with?
Is it true that the Briggs engines use an easy spin or compression release to make engine starting easier?
Yes, many Briggs & Stratton engines feature an easy spin or compression release system designed to make starting easier. This system reduces the compression pressure during the starting phase, allowing for smoother and less strenuous pulls on the starter rope. By alleviating the initial resistance, it helps ensure that the engine starts more reliably with less effort.
18.5 Briggs and stratton engine will not spin fast enough to start?
If an 18.5 Briggs and Stratton engine is not spinning fast enough to start, it could be due to a weak battery, bad connections, or a faulty starter. Check the battery voltage and ensure all connections are clean and secure. Additionally, inspect the starter and solenoid for any signs of damage or failure. If these components are functioning properly, the issue may lie within the engine itself, such as compression problems or fuel delivery issues.
How do you adjust the coil on Briggs and stratton 17.5 engine?
Spin the engine until the two legs of the coil lines up with the magnet on the flywheel. Place a standard business card between the the flywheel and coil and let the magnet hold it in place between the two pieces. Tighten the bolts down. Spin the engine and get the business card out and you're ready to go.
What type of oil filter does a craftsman yts riding lawn mower need?
The Craftsman YTS riding lawn mower typically requires a standard spin-on oil filter, often compatible with the Briggs & Stratton or Kohler engines depending on the specific model. It's essential to check the owner's manual for the exact part number or specifications for the correct filter. Commonly used filters include the Briggs & Stratton 696854 or similar models, but confirming with your mower's details is recommended. Always ensure to replace the filter during routine maintenance for optimal engine performance.

Why do Jupiter spin around the sun ten hours?
Easy answer: it doesn't. Jupiter revolves or orbits the sun in 11.86 years, or about 4,226 days. The rod 'Spin' does not mean the same as 'revolve'.

Easy the Mad Hatters Teacup Spin
Does the baseball affect how easy it is to hit home runs?
No but it does matter where the ball is hit, if it is hit on the seams it will have more spin and won't go as far, and if it is hit with just smooth surface it will go farther with less spin.
