Ok, if the engine is running fine, idles well, runs good at WOT, don't worry about it. Most all of my 2 stroke engines ooze oil out of the front. it actually keeps the front bearing lubricated much better and helps flush out any dust or debris that get into it. A number of years ago some companies started catering to those users who wanted less messy engines. But before then all the engines oozed oil out the front. Bushing engines still do so today and some brands still use open bearings without seals on them. The front bearing lasts a lot longer if it gets a steady flow of oil through it too. I tend to worry a lot if oil isn't oozing out of the front bearing area on my engines.
