First I removed the air cleaner cover and removed the the old air cleaner and installed the new one. I then removed the coil assembly from the unit and installed the new on, and gapped distance between the coil and the magnets on the flywheel at 0.024 I then replace the spark plug and gapped the new one at 0.030 and installed it in the engine. Engine runs very well now.

Engine was on a pressure washer...Started it and just did not run well...I run nothing but non-ethanol fuel and empty the fuel bowl after each use so, a fresh plug, air cleaner and a few missing parts had my Honda engine running like a top...One pull choke and second pull start...Took all of 15 minutes to get in shape...Love my Honda small engines and eReplacementParts.com provides me OEM Honda parts at a reasonable price...
