Have a question regarding a 1979 Mercury 50 HP electric start.<br />The motor runs great, but every now and then the very first crank is very slow, followed by normal speed and then fires up.<br />Is this normal for a 2 stroke ?<br />I thought it was to do with excess fuel being drawn in to the motor and the starter trying to crank against a full combustion chamber.<br />I also thought that there may be water in one cylinder which may have corroded the cylinder wall and the piston was trying to push through<br />this... I would have thought in this case, that the motor would not be running as well as it does if this was the case. How do you check ?<br />Battery is fully charged, and connections look OK.<br />I can get 5500 Rpm out of it and it idles perfectly on all 4 cylinders. No steam evident on muffs, which I would have thought would have to occur if water was present.
