idle problems

[KeyWestMan]

I have a 1988 50hp evenrude eng that will not idle. It will start at a higher rpm, but when I set the engine to idle position the engine stops. I can restart it again at a higher position on the throtle and the engine stays running until I set the throtle back to its normal position. Please advice on the problem.

Check compression, may need to have carbs cleaned and check for air leaks on intake.

Most likely the slow speed needel valve.Not sure if that screw is on top of the carb or comes in at an angel on your model,but its the screw on top of the carb.Pretty tricky to set those.Start with the middle carb.1/8 turns at a time
