HELLO, I'M NEW TO NITRO RACING AND I HAVE A QUESTION THAT I HOPE SOME ONE COULD ANSWER.

I HAVE A NITRO CEN CAR THAT SPITS FLUID FROM THE EXHAUST IS THIS NORMAL OR A MAJOR CONCERN?

THANKS.

Its normal depending on how you tune your motor. It shouldnt be blubbering, but spent castor oil is a by product of the glow fuel, its not supposed to burn, if it did your motor would be ruined.

If its new then if say its rich , try leaning the HSN a little at a time till it picks up and stops spluttering
