Was motor stored with old gas? Are you running old gas or new fresh gas mixed 50 to 1. If you are using or stored old gas you probably need to rebuild carb and possibly fuel pump. Remove bowl screw on carb and allow gas to drip into a clear glass jar. Can you see water or other debris in it? Will bulb get hard on fuel can without leaking gas at carbs?

Crimson<br />Just for fun try a new prop. Your current one may be spinning through the hub.

Re: mercury classic fifty {86 model

you can test the hub with finger nail polish or a permanant magic marker. Mark a line on prop and prop nut, run motor then recheck to make sure line is still lined up. If not the prop is spun and you will need a new one.
