If you want to have something to think about, many brands of spark plug wires and plugs do not work well in that engine. DENSO or NGK plugs and plug wires are the only ones which are reliable from my experience.

It is definitely not an air or fuel filter.
Thanks Brian for your tips! The replacement plugs and wires I installed were NGK.
