I got a hpi baja 5b with a clutch issue, possibly. it starts but at idle, both low and high idle, the truck wants to roll as in the clutch is engaged at idle. it has a veritigo clutch. with engine off the car will roll freely. spring is there, bell house is true round, and everything is looks like new. I just bought this car used. how tight do the bolts on the clutch shoes have to be?.
