got a viper dead spot on start

[696viper]

hello i have a 2002 viper if you just give it full throttle right out of the gate if will boog down almost stall but if you slowly raise the rpms it will run fine if you are ridding its fine only from a dead spot what could be causen this problem

i have cleaned the carbs try it again what about exhuast vavles would they have any thing to do with that

open up more the pilot screw

Try flipping the choke on/off and see if it picks up faster. If it does, than the pilots still have blockage in them.
Many a time I couldn't get the pilots clean by spraying through them, I have to actually run a small wire into them to get the gunk out.

when u have em out u should be able to look right through em and see some daylight if they are clean, if thats not it then open your screw a little

Stock on the viper is 1 7/8 out on the fuel screws. Try them all at 2 turn out. Also make sure the carbs are synced. Sync to the middle carb. Plenty of info on that. Let us know how you make out.

[696viper]

Yes, stock pilots are 45's.

Try the choke trick first to see if we're on the right path.
