AND keep a heads up and do not forget to re-install the breather tube into the rear of the air box.
If you forget this the carb WILL suck unfiltered dust dirt straight into the carb throat on that model engine and the rings will go fast. I've seen quite a few of them that Bubba overlooked such.
Also as Ke4 mentioned set the valves are a snug .004 and it's quite common for the .004 to become loose after few hours of operation and require a re-adjustment. Usually the second time adjust will hold.
Also just adjusting the valve lash normally will not stop oil smoking.
Take a look/smell at the oil level and also make sure it's not gas contaminated.
Might even think about changing the oil to straight 30w and do not overfill.
I've seen some of them type engines that a head gasket would start seeping/leaking and at first would produce intermittent smoke and then progressively get worse.
Also hang onto your OEM Nikki carb. The clone carb replacements are iffy.
There is some good on-line info about how to re-build those Nikki dual throat carbs and as Ke4 mentioned/hinted the o rings on everything inside the bowl needs replaced usually.
