This 1997 stx has used up 3 engines all with #3 piston melted on exhaust side.
the latest is it will not accelerate at wot and sounds as if it is missing. Pumping throttle gets it going and will run wot all day until you let off. Engine has no mods have gone over carbs countless times. Why is it always # 3 I have read several posts and some answers but the only one that made sense was from Group K about torsioing of the crank. I could not find a fix can the 3rd carb be re-jetted larger or does some one know what the fix is. Thanks any info would be great
