The factory advice from Bax should be followed 100%. one point is really the KISS principal if cannot see or feel oil coming out the exhaust on any engine 4 strk , 2 strk

over the engine. it will have a short life. and of course exceeding the max rpms stated in the directions which is usally caused by under -propping martin
