2002 mercury 200 2 stroke will not idle in neutral

[Bchappy]

Just bought -150 hrs-always run with ethanol fuel and seafoam. Maiden voyage idle was set high wouldn't slow idle but ran great. I left it idling for half hour then another long idle down the canals twice. Today after sitting on anchor it would not stay idling in neutral-run 10 seconds and die-restart same-had to punch it into gear to get moving. I noticed that it didn,t idle fast anymore. Could it be plugs from all of the idling? I will run ethanol free fuel going forward. Finally is seafoam safe or recommended for constant use?

I wouldnt use sea foam to often. Check fuel filter/plugs.

I used for 10 years with no wrenches on a 2002 90 2 stroke at the 1 oz per gallon recommended rate. Why not say you??????? BS sounds like to me. Too many happy users out there on different types of equipment sites.

Yep....can tell you 2 ounces per gallon doesn’t work so well in a 2 stoke golf cart running 128:1
