Amber like material in exhaust
Ok, this one is baffling. I just pulled both my 525EFI's for some winter work and both, including the one rebuilt last spring have a bit of amber like material in the exhaust ports of the heads. I searched around online and found a few other people with the same thing, but no answers on what it is. Maybe something from the fuel? Anyone have any ideas???

I see said the blind man . Anything laying in the exhaust ports should have passed through the combustion process and hence be exhaust smoke or carbon . My conclusion is the same but i'm just a nobody trying to help you . What do your spark plugs look like ? They usually have a story to tell .
