Henigin's Small Engine Repairs

   Mentioning Ethanol and Poor Gasoline to a customer is somewhat confusing. The images here show the damage that ethanol does to carburators and the fuel system to a engine.

Ethanol does provide a cleaner burning engine, but it also raises fuel comsumpsion.The white deposits shown is deteriation of metal from ethanol.       The particals of metal are then mixed with gasoline being consumed. The deposits of the particals clog small metering holes in the carburetor or burn and collect on sparkplugs, cylinder head and the piston.

These deposit cause hot spots on internal parts that eventually lead to hard engine starting,engine running eratically and backfiring thru the carburetor.

Ethanol also atracks water in fuel bowl and metal that it comes in contact with.

Gasoline over time loses its viscosity in a short period of time In as little as 10-15 days in humid weather. As this ocours it leaves gummy deposits on the bottom of fuel bowl, carb float, valves and close the metering holes in the carb where the engine will not run until the carb. is cleaned.

Fuel Stabilizer and other additives help with ethanol problems.

Fresh gasoline purchased every 20 - 30 days is a better choice. Mid-Grade or High Octane fuel is recommended by all small engine manufactures.
