    1986 Johnson 175 HP

    My VRO pump is leaking when I pump the fuel bulb. I plugged off the oil side and am premixing my fuel. Can I get some suggestions, should I rebuild or replace with a fuel only pump? If I go with a fuel only pump does anyone have any suggestions on a good pump? There are so many on the market.

When I slowed to pull into the harbor I noticed a slight miss when I went to speed up a little. I got home and fired it up and had a weak battery and I...
