2000 Johnson 200 hp starts good, idles good, great at WOT.
After idling 10 or 15 minutes in no wake zone, starts to run rough, rpm's drop, spits and puffs smoke, and dies.
Only restarts after four or five attempts.
Will run all day at higher rpm's, but any extended idleing causes death.
Of course this happens when close to pilings or in front of oncoming large boats.
No other members of family will accompany me any more. Best friend is reluctant.
Any help appreciated.

Will it keep running if you pump the primer bulb ?? You can also do a cyl drop test on it at idle to see if it's hitting on all the cyl's.
