please explain
me and my friend were at a race and his truggy was lean boging, we brought it into the pit area and it wasn't that hot but i noticed it wouldn't idle, so i raised the idle screw a couple hours at a time until it would hold a idle(i think about 4 hours total) and then after the engine reached alittle over 200 i checked the low speed on the box and it checked out fine, we put it out on the track for the 20min main and the engine ran great the whole time with no lean bog at all. did by raising the idle richen the low speed? any help would be great if u have experienced this or understand
