When I run at above idle it does good and at full throttle. But when i let it idle for any length of time it wants to bog down upon going again.<br /><br />A little bit of history:<br />1992 3 cylinder 60 hp<br />It started running a little rough so i put seafoam into the gas tank with a full 25 gallon tank<br />I took off the couling and noticed a head bolt sitting in the bottom of cowling. it had been there a very long time ( I could see the old water marks ) I did check the cylinders psi before i noticed the head bolt was gone and they were all at 100 psi.<br />I'm not sure what the previos owner put in for oil but i am using johnson/evinrude oil.<br />When loking at the spark plugs they are all alitle moist but not sajuated.<br />this is a tiller modle and the smaller nob on the end of the handle has been turned before i relized it adjusted the idle?<br />Sorry for the long post I just want everyone to know the facts. Should I run carb cleaner into the carbs? when I had the head off to easy out the broken head bolt, the cylinders still had the honeing marks and didnt look to carboned. I did replace the head gasket and the bottom 6 bolts.<br />Thanks for any info
