full tilt viper
New member
Just started my piped viper for the first time this season.Normally it will start after about 6-8 pulls. This year it took about 30 pulls ( strange ) Once it started i went to full choke , no problem. Then went to half choke started to clean up a bit seemed normal. Then went to no choke. It cleaned right up as usual sounded good for about 5-8 seconds. Then it would not hold idle and stall. When I'm on the gas from 1\8 and up it comes back. But as soon and you go to let it idle it starts to run on one cylinder then stalls. As soon as i begin to lift up slightly on the choke just into half choke the motor wakes right up a 3 cyliners are firing soungs great . I ran fuel stabilzer through at the end of last season and fogged the motor.I know the idle is set right the sled was running perfectly when i put it away.Any thoughts?
