Re: '97 115 won't idle and spits all of a sudden
you should be able to find a head for $25 or so...
you dont want a hot spot.
you could file the high spots down and make sure you absolutely get all the steel pieces out of the aluminum!!!!!!!!!
but for the price of a used head...id just get another...
dont know if carbon was your culprit...
when the piston comes out, you might have more clues...you can look in the ring grooves and see if it is loaded with carbon.
I have a 1997 90 hp but it is a 60 degre V4...and the amount of carbon =gunk in the exhaust housing blew me away...almost totally choked off two passages..

Do you think all that carbon was caused by just years of not being decarbed maybe? Does that look like a lot of carbon? I'm not experienced enough to know if that's a lot or a little, I was told it was a lot.
I thought anything lower than 5500 WOT was lugging it, but I guess 5200 probably wasn't enough to cause that much carbon.
Do any of you experts think that head can be salvaged, or should I expect to need a new head? Also why aren't the inside of the heads/combustion chambers full of carbon? I figured they'd carbon up too, but they look clean as new.
Thanks.
