Built to Perform
Renew Your Power Equipment
Adding a new Ironton OHV engine to your power equipment is like giving it a new lease on life. The Ironton Engine's cast iron cylinder sleeve, dual ball-bearing crankshafts and internal oil splash enhancement system mean that it is an engine you can trust. The low-oil shutdown system turns the engine off if it runs low on oil, preventing serious damage or failure. The engine's recoil start has a compression release that helps it get going on the first pull.
Adaptable Power
The Ironton OHV engine can cover many of your small engine needs, including log splitters, pressure washers, and many other projects. It is easy to install, thanks to its unique design.

Warnings + Disclaimers
High Altitude Operation
CAUTION: Operating at an altitude of greater than 2000 feet (610 meters) may affect your engine's performance, fuel consumption, and emissions. To remain emissions compliant and improve engine performance at higher altitudes, a high-altitude kit is required. A high altitude kit includes a carburetor jet resized to help correct air / fuel mixture at altitude. To order a high altitude kit, or if you have additional questions, contact us at 1-877-234-6869. Please note, engines with the high-altitude kit installed operated at lower altitudes could cause severe engine damage and affect emissions compliance. When modified, a tag or decal should be added to the product stating that a high-altitude kit was installed and to remind you to re-service the carburetor (re-jet) when operating in lower altitude environments.

Break-in procedure?
How should this engine be broken in, I don't see any recommendations in the manual.
-
mickkjhc· 9 years ago
My manual recommended draining the oil after the first 5 hours and putting fresh oil in. It's probably good to go easy on the engine and not throttle it up too much during the first 5 hours too.
Helpful?
-
IrontonExpert6· 9 years ago
You would change the oil after the first 5 hours of use for the initial break in. The oil should then be checked every day or after 8 hours of continuous use and add oil as needed. Regular maintenance, the oil should be changed after every 50 hours of use.
