NEW ENGINE BREAK-IN

Your OFNA engine is extremely tight when the piston is at the top of the stroke and turning the crankshaft by hand.
This is normal for a new ABC type engine
tapered for a tight fit. As you run your engine, this tightness Should diminish. There is no cause for alarm , because
as the engine warms up, the brass sleeve will expand faster than the aluminum piston and the engine will turn free.

As with any new engine, there are many high spots and tight fits in the matching process . High spots create hot
spots that must be broke-in. Therefore, the break-in process is very important to provide good ser
