cold start even when hot

[81_chapparel194]

~~my 1981 90 hp evinrude has a cold start on every restart. my normal cold start routine... run fast idle lever up to "start" position hold key in for 3 seconds then turn to start.. engine fires up after cranking 5-8 seconds. lower fast idle lever to about half way and let it run there about 30-40 seconds or until idles smooth, then drop in gear and go. problem is every time I start it up I have to do the same process even if Its 20 times a day I start it up.
my first thought was dirty carbs. puled carbs and cleaned them EXTREMELY well soaking in cleaner for 24 hours then running small strand of wire thru every orfice in the carb followed by compressed air. still had problems so I took them to my local evinrude dealer for a cleaning and rebuild. installed them and checked the link and sync. still same problem...compression tested 105. 105 102 105 all spark jumped 7/16 gap with no problems

Hold the key in once when cranking it over until it starts. Then feather it to keep it running. Not just the 3 sec.

Have you ever de-carbonized the engine with sea foam or other decarb product? may want to try that first........it could also be your reed valves causing a low crankcase pressure which would cause a hard start condition.

As above dont press key in until you have turned key otherwise you will lose pump pressure and will probably flood it.

You could also check that your two thermostats arent stuck open

i have not used sea foam and I have thought about the reed valves. how do I test those?
