not supposed to run regular in those motor ...look like u maybe found the trouble ......detonation could create the burn down ...does the air box still untouchCanadian Viper said:Machine is at a friend garage, will take a pic Sun, and check that. starting to wonder if the ethanol 10% they added here took its toll. Burnt 3 tanks of premium so
far, but today burned regular. Most of last year I burnt regular as I have done all its life

The reason the center one started it too, is also higher compression and the gas is too low of octane. The pto looks fine because its lower on compression, not making as much heat. The mid range cruising on the needle circuit is the bad spot on a viper, lots of ign timing puts extra heat in the piston, higher compression makes more heat,thats why I have been preaching to raise the needles on a bone stock sled.
You NEED to richen up the needles because the gas is very low quality these past couple years, your paying more(gas prices) for less quality......![]()
