Welcome to MBc, Mowerman. I'm certain we can help you with your Honda Engine. I would suggest that you first read all of the 'Stickies' on the Forums, especially the ones at the top of this page. they contain everything that should get you in the right direction. then, make generous use of the search Function. If you are still stuck, go to the proper Forum (most likely 4-Stroke, maybe 2-Stroke) and fire some questions at the resident gurus who usually reside there. Good Luck.
