Smoking when in idle

[porl_hopkins]

Hi am a total noob and have a MTA4 S50, just trying to tune it. Got the HSN pretty good, trail of smoke and engine temp at around 220 - 230. Trouble i got is it is VERY smokey on idle and upto 1/4 throttle.... any help would be apprecuated. Thanks in advance

Could be that your low speed needle is too rich. When you launch the car from a stop to wide open....does it hesitate and then take off? If so...lean your LSN 1 hour at a time until it gets better.

Its going off pretty quickly. I have been leaning it off a fair bit, but now it is stalling when I pull off. Going to wait for the rain to dissapear and have another go

It Should be smoking, because unlike gasoline engines which burn the fuel completely, nitro engines only burn some, vaporizing the rest. so if there is no smoke, then you are waaaayy too lean and could mess up your engine
