06 Fusion top end power loss

[Burgy]

I have replaced the carb boots, jetted down to 410s, cleaned power valves, new plugs gapped at .025. I still have a slight power loss when I hold it to the bar. Not as bad as it was after I did all the work but I still have hesitation. Any thing els I should look into?

are the bellows inside your power valves good?

Yes the bellows are fine. finally got some thime this wk end ran it 120 miles same thing going on. Ran good first 60 miles but got back to the same power loss as when I started. Took plugs out and one side looked good with new jetting but the other not so good better but black. Can any one tell me what the number of screw thurs should be for factory adjustment? Tried locating a service manual but no luck.

Did you hook up the vent lines from the carbs to the airbox? That will cause the rich condition.

I'll have to check I do not remember doing that. I did run it for 120 miles this wk/end. I checked plugs and cluch side was good. Chain case side was black. If the tubes were not hooked up wouldn't both side still look rich? Any ideas where I can get a service manual for thsi sled??
