RE: DA50- Anybody Having Trouble?
My DA is a DA-50-R.. came from the factory a month ago.. I guess they may have put the improved parts in yours.. Cool thing of them to do.. I am sure that increased oil content will decrease your RPM's because Oil is less flamable than Gasoline... I think Thats why many brake them in and then switch to Synthetic 80:1 or 100:1 for more power.. I personally am running about 50/60:1 Amsoil for break-in and I am still on my first gallon.. Some will curse me but oh well it is my engine, it runs fine and I don't want to hear it... I will run a leaner mixture a few gallons down the road...
