I've got an '02 Viper that seems to have the center cylinder acting up. At low speeds it acts like the plug is fouled and at idle you can pull the plug wire with no effect on the motor, but at full throttle it runs great and you can't tell anythings wrong. I changed the plug twice and both of them came out somewhat clean and dry like they had been burning.
Everything on the motor is stock and the only thing I've done recently is take the carbs off, clean out the jets, and re-adjusted the fuel screws. They were at 3 turns out, specs call for 1 7/8, so I put them at 2 just to be safe.
I've put about 15-20 miles on before it started doing this. Ran like a champ right after I put the carbs back in.
Can anyone give me a couple good starting points to check before I start digging in deeper than needed.

sounds like carbs are not totaly clean, i would disasseble clean all jets high speed and low speed and blow air through all the passages and jets alot of the time they have clear jelly in them if thats the case then you will need to clean entier fuel system and put in fresh fuel and make sure there in syc

I could feel the plug cap shocking my fingers at idle when it was off so I'm pretty sure that part was o.k.
I'm thinking it sucked up too much snow. After being in the garage overnight I started it up and it ran fine again. Didn't ride it thogh, just hung the rear end and spun the track. Purred like a kitten.
Hopefully it'll stay this way.
Thanks for the replies.
