I have a '93 70HP Evinrude. I have trouble starting the engine when it's cold. It usualy takes 10 - 20 times to crank it until it starts. But, when I manually add some gas in the cylinders it starts right away. The motor then starts and stops with no problem, but If i leave it 15 - 30 minutes to settle, then it wont start again.
Can you tell me what should I do to solve this problem? I already know that the compression is good, the sparks are good and I have new sparkplugs.
