This motor has very few hours and has been sitting in my shop for a couple of years. Checked oil, very good. Put it in the tub and it fired first time. Minor adjustment to the idle screw to bring it up. Runs very smoothly with strong tell tale. I know very little about this model. Checked head temp and it is 155.
A little hot compared to the two strokes. Is this acceptable?
Thanks.
