Hi guys,I am having a problem with my 2002 viper,here are my specs
Aeen tripple pipes
v force reeds
tempa flow
162.5 mains
other jetting stock
cpr heavy hitters primary
47 secondary silver spring
When I come to a stop my sled losses rpm and backfires then rpms come back to normal and about 10 seconds later it does the same thine about 3 to 4 more times then it is fine,it only does it when it is at operating temps,the sled pulls fine under load,It is the pto cylinder that is missing I have cleaned all the jets,checked the reeds,changed plug,changed fuel screw settings,did a compesion test 130 psi,checked out plug cap 6.5 ohms,plugs are perfect,the only thing I can think of is swapping over the coils and see if this tells me if the coil is bad,If anybody could give me any other ideas that would be great.
Thanks Steve
 

Check your float level if you get the carbs off again. Might be to hi. Maxdlx
