I have an 84 140hp evinrude and I can't get it up to speed. I changed the spark plugs and I have new fuel and oil. I just don't know what is wrong with it. I did have a problem with the fuel lines where when I was at full throttle. The bulb would get compressed and the engine would die so I disconnected the fuel tank vent and that helped a little well atleast enough to get back in. I never did find out where the blockage occured however this problem hasn't happend again. So I am not sure if this is the culprit or it is something new. I am also having trouble with the tilt trim. I was told to replace the tilt trim oil because it had been like 3 years since it was changed and then when I did that it hasn't worked since. The sound of the trim motor is running but nothing is moving. I tried to prime it by lifting the motor and putting it back down manually but it still won't work. I am not sure how to bleed it to get air out if that is even the problem. Please help.
