"The lawnboy experience"
I like that, my mower still smells like a good lawnboy should but it does smoke very little. On a windy day you can't see any smoke but if its almost still it will be slightly visible. My mower is running a bit lean (air/fuel wise)though due to a leaky seal I should've fixed last winter. The same gas and oil mix in my chainsaw does smoke all the time as its running richer.
I should pull the plug on the mower as I bet its a light tan colour, I doubt anyone with an obviously smoking lawnboy has a plug that's not black.
