Good day people.
I have recently bought a second hand evinrude 70hp outboard, 1982 about 6 weeks ago. When out of the water on the trailer it starts fine, goes into gear and revs well. but when i put it in the water (sea) and start it it ticks over OK, but as soon as i try to put any throttle on it, it dies, just cuts out. I have tried to get some revs on it, and it will drop into gear and tick over and run at about 3knots, but try any more revs and it cuts out? I stripped the fuel pump and noticed the plastic plug and spring was siezed, so released that and cleaned it all out thinking problem solved, but no still the same. I have took the front cover off the carbs and put in some carb cleaner and left it for an hour or so, started it up and noticed it now races ever so slightly, more than it did before.
This was a month ago, started new thread now as i have not been able to get down to the boat due to bad weather, i have been able to get to the boat now.
Have now done a compression test and have 130 (top) 135 (middle) and 150 (bottom)
i replaced the spark plugs, which had a .70 gap, and put a .30 gap on the new ones.
I have replaced the prop to a 15 pitch as i was told that may be the problem.
I had it in the water yesterday and can now get a few more revs than i could before, but it still cuts out, so i have removed the carbs. They look pretty claen to me when the bottom bowl was removed. Can some one explain what i need to do to them to get them ship shape.
Thanks
Peter
PS if anyone has any other ideas as to what the problem may be please feel free to comment.
