Hi, There should be a sticker on top of the engine someplace that will give this information.

If not we will probably need your engine serial number and/or your year to try to help you out with the specs.

You should be running NGK LFR5A-11 spark plugs gapped at .043" (1.1 mm)

Don't run Champions or you motor may run like crap...
