you should blow the engine very well with dry comp[ressed air,not local gas station air. you should use a high quality AFTER RUN OIL,hobbico is good. theu say this becuase nitro is very corrosive and will actually make the crank shaft rust. take a clean/new piece of fuel tubing (about 4" long) and slide it over the end of the after run oil and you can install the oil that way with out spilling it.
the reason they tell you not to put it through carb is it has inhibitors that bond to material and will cause the o-ring to swell up. dont worry much about this with the fuel tubing on the end and it only takes a few drops nto a full crankcase.lol
you should only use after run oil if you are putting the engine away for a while. if you use a good fuel like sidwinder it has inhibitors in its oil so short no run stints does not hurt the crankcase or shaft,but it dont hurt to use the aro every time,better safe than sorry.
p.s. dont forget to spin over the engine to coat all internal parts evenly.
