Decarb? yes or no

[McKenzie]

I've read a lot about decarbing outboards and it sounds like a good thing to do. You usually increase performace and are properly maintaing your engine by doing this every so often. However, I haven't heard too much about decarbing I/Os. I have a can of SeaFoam and was wondering if I should pour it down my carb or not. Thanks for the help.

Re: Decarb? yes or no

McKenzie,<br /><br />I/O's have a completely different type of combustion that most outboards.<br /><br />Outboards burn the lubricating oil along with the gasoline. This tends to "coke" up rings and build carbon deposits. Thus the need for decarb. <br /><br />Four cycle engines do not do this. The lubricating oil does not enter the combustion chamber. At least it's not supposed to. <br /><br />Sea Foam, seeing that it's a fuel stabilizer too, ceratinly will not hurt anything.
