I had this same problem with the 1.1 version. I just downloaded 1.3 tonight and was hoping this was fixed.

The way I worked around it in 1.1 was to use use my fuel mixture control (I have a CH Flight Sim yoke with the 3 levers on top) to reduce flow to around 100 PPH while on the ground. I have no idea if this is realistic or not, but I was so tired of not being able to park on the tarmac (even with brakes) that I didn't really care.

I guess I will keep working around it in 1.3. Honestly, I had very few issues with 1.1 and once I figured out what was causing me to zoom across the airport, into buildings, trees, and other planes, I really enjoyed flying the C130 around.
