Hey board,<br />Rebuilt carbs on 150 Fast strike (six JB)runs pretty smooth but has a backfire every 5,6 seconds is this timing or float not quite right?<br />Also made a run on the water and only getting about 4500 out of her.<br />Checked plugs and had a few dry ones so went back into carbs double checked float level fixed the problem two were off by a hair.Still have backfire.
