When building a clone engine, you‚re most likely wondering how to set timing. There are a couple of ways to accomplish this. Depending on your preferred engine configuration, you can use the piston position to set the timing. Or, you can use a Billet flywheel with adjustable timing. Whichever method you choose, it‚s important to follow the instructions carefully. This article will walk you through these steps.
Offset timing key for clone/predator/ducar engines
If you have a clone, predator, or ducar engine, then you‚ve likely wondered how to set the offset timing. First of all, you‚ll need the correct flywheel key, which is included with the engine. Alternatively, you can use a standard flywheel. In any case, this step is critical for your engine‚s reliability.
Billet flywheel with adjustable timing
A new Billet flywheel with adjustable timing is an excellent choice for your clone engine. The Briggs PVL ignition is SFI certified and made specifically for Honda GX200 and Clone 196 engines. This flywheel features a low-drag fin design to help reduce air drag. While it doesn‚t add much horsepower, it will help you to maintain the timing throughout the power curve.
Most non-arrangeable ARC flywheels come with 8 degrees of advance built in and require no flywheel keys to install. The timing is set BTDC to allow gas to expand to force the piston down in the proper rotation direction. Installing an adjustable flywheel will help you to improve the timing and revs of your clone engine. The Briggs Animal PVL Electronic Ignition Coil is also available.
