Bought a NGK iridium sparkplug online for Honda EG B16A DOHC, however received a sparkplug which has a longer reach than it should b. Seller claim closer to piston more power. ZTH's sifu please advice. Thanks!
Pic 1 - Remove the original regulator with 2 screws, first remove the two hose that is connected to the regulator one with the clip and the other one is the vacuum hose.
