Re: Had my little putter for a year now...
I simply rinse the bottom end with diesel fuel or good solvent like MEK or lacquer thinner while turning the crank until all the grit is gone, draining and refilling often until it drains clean. Once its spotless, I soak it in straight two-stroke oil a couple hours to lube the rod and mains well before draining the oil and assembling the top end. I do this on ALL my new engines just in case. I have never had a bearing or engine failure yet. (knocks on wood)
You should check for proper assembly also while you're inside the engine. Pay special attention to the crank seals and make sure the small drive gear is on straight and not wobbly.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
