Hi Atomik,

Although all engines have been washed by supersonic washer before selling. But I still would like to suggest you to do some simple wash.

You can take off the head button and rear plate,use some fuel to drop from carb and sleeve place. Then rotate the crankshaft and let the fuel move off from the back plate place. This is base wash in my opinion.

Of course if you can take apart fully to wash it that would be good,but I afraid you may can not take out the conrod from crank when the engine is brand new. When you break in engine with a very rich setting the engine will clean itself. So it's different views if it's necessity to clean engine fully before break in.

Regards,
Dino
