The car does drive, I did get it moving briefly but then went to full throttle without my help. You say it's running learn, it's pooring out fuel from the exhaust.
If I'm totally honest, I've had my buggy for little over a year now and am still not which is my low speed needle and which is my idle. also don't know factory settings for these 2.
I own a HBX VRX - 2 Nitro Buggy.
Cheers.
