    1975 25hp johnson

    I just purchased this motor and when going forwards it surges (jumps) about every minuite or two. It's fine at idle and reverse. Any help would be greatly appreciated!

    Motor surges(or jumps) when in gear going forward, about every minuite. It's fine at idle and reverse, could this be timing, points or spark plug coil? Any help would be greatly appreciated. <br />Thanks!
