Most people check for proper engine spark by removing the spark plug, attaching the plug wire and grounding the plug to the engine while spinning the engine over and looking for a spark to jump across the spark plug gap. This method is not always reliable. The amount of voltage needed to jump the spark gap set at .030″ with the plug removed from the engine is about 2000 volts. The amount of voltage required to jump the same plug gap with the plug installed in the engine and operating under operating conditions is about 8000 volts, so it is possible to see a spark with the plug removed, but not have a spark with the plug installed.
A more reliable method is to remove the spark plug wire cap, and hold the spark plug wire approximately 3/16″ away from the spark plug and spin the engine over. A good ignition system will produce a orange/blue spark from the end of the spark plug wire to the spark plug. The problem with this method is it is easy to get shocked and hard to turn the engine over while trying to hold the end of the plug wire 3/16″ away from the plug. The benefit of this method is it is more reliable then the first method and doesn’t require purchasing any special tools.
Another method for checking the ignition for proper spark is to purchase the Briggs & Stratton Spark Tester, part #19368. This tool can be used to check for spark with the plug removed and using no hands, so the engine is easy to spin over and there is no risk of being shocked. The tool can also be used to view the spark while the engine is running. This is very valuable when trying to diagnose a rough running engine or a engine with intermittent problems.

how to adjust the governor on a small engine and how the governor system works

SURGING ENGINE: This is a dirty carb, not the governor.
99% of all snowblowers, tillers, generators, log splitters, pressure washers and other equipment are designed to run safely run @ 3600 rpm max.
Mowers engines are designed and can easily handle a max of 3600rpm…However lawnmower blade speeds are goverment regulated and since the blade is directly connected to the engine they are sometimes limited to speeds closer to 3200rpm. Check your mower mfg for specs. Some mower manufactures lower the rpm only to reduce noise from the engine.
Looking for a little clarification on why this mower has the foot controls only on the right side and not the left like most riding mowers do. The owners manuals I have found online all show the foot controls on the left side (see link)

This is my first how-to video that documents the repair effort of my Craftsman lawn tractor with a Briggs and Stratton Intek V-Twin 21 HP engine. The engine began emitting a loud tapping sound from under the rocker cover. Soon thereafter, it began running unevenly as if one cylinder was no longer firing. This video reviews the diagnostic and repair procedure to replace the bent push rods and cylinder heads. It also covers adjusting the valve clearance and has some tips and advice to help avoid this problem on your air-cooled engines. Please feel free to leave comments on how I can improve for future videos. I consider myself handy, so if you would like to see other repair videos, let me know and I can see what I can do. Please like my video if it provided valuable information for you.
