Hi all,
I have a cen racing fun factor 2 monster truck. This thing has given me a bunch of problems. The one thing I noticed was that just idoling for 10 seconds it spits out raw fuel. I put everything to the way it is supposed to be stock and this thing eats gas. Then when I lift the gascap while it is running the back pressure comming from the exhaust pipe spits fuel everywhere. I thing that the exhaust is causing this car to be a gas hog.

Any suggestions,
Thanks
