Hi guys i have a 225 optimax it is a 2005, When i start it in the morning it idles rough, like its stalling, it has stalled out on my while idleing once, after i run it it idles great the rest of the day, i just took it in for a tuneup, new plugs and everything, Any ideas what could be causing it? Any help is appreciated, also i have warranty left on the motor so I'd like to get it fixed, doesn't seem to serious cause other than that it runs like a champ
Was this occurring "before the tune-up", or did it develop immediately thereafter?

it happened before the tuneup and thought it was just plugs. Any help is greatly appreciated.
Check the spark plugs that were installed.
Standard 225: NGK IZFR5G (.031-.033" gap)
ProXS 225: NGK IZFR6J (.031-.033" gap)
Clean, correct, and properly gapped plugs are critical to good idle quality.
