Yamaha 9.9

[Ryoushi]

Hey, i have a 2005 and it won't idle. I'm thinking it's from sitting too long. I have fresh gas in it and ran some sea foam through it but it's still idling really rough. Any tips on rebuilding that carb?

Not off hand... take it off the motor and dig in!

Try a heavy dose of Seafoam. I keep a portable 3gal tank with 2gal gas/1 can of seafoam. When my 9.9Johnson acts up (idle while trolling) I hook up the small tank, run at WOT for 5-10 minutes and then troll with it. Cleans it right up for another month.

I have had the same problem with my 9.9 yammi. Started running yamaha ring free in about every other tank. Never had a problem since.

Stuff is pretty spend, but you don't need to use very much.

think it is like 1oz. per 10 gallons when used regularily.

Ring Free is some good stuff... no doubt about it.
