Nitro rc question?

Question

my new nitro rc buggy spits fuel out of the exhaust but barely smokes i know if it smokes alot its too rich but if it spits fuel its too rich so what do i do ?

Answer 1

ok i know all of mine have spit something out of the exhaust but ive always thought is was part of the fuel that couldnt be burned i have a little blue smoke out the pipe and it runs awesome so i dont think i would worry about it i tune my motors with temp gauges and by the sound and how they act too lean its a high rev and no smoke and high temp too rich smoke and sluggish accel and low temp so just idk if the stuff coming out your exhaust is fuel or not id say no   i hope this helps
