Review on πŸ”§ Honda 16590-ZE2-812 Stay Choke Control: Optimal Choke Functionality for Efficient Performance by Samuel Nguyen

Revainrating 5 out of 5

Ideal for Harbor Freight Predator 420 clone

This product is perfect for Honda GX390 or Harbor Freight Predator 420 clone (shown). On the Predator 420 it will not fit in a standard air intake, but will work great with a performance air intake. This product also replaces the thick metal washer that you normally need to use on these engines to ensure proper idle when you switch to a power inlet (the idle port is open on this washer). Paper gasket used on inlet box, you don't need to buy additional gasket for this purpose.
