[NSRCA-discussion] Fuel leak

[adriancwong at earthlink.net]

Merry X'Mas to all.

I have a 160 DZ suddenly developed a fuel leak on the back of the engine between the back plate, the carburetor, and the carburetor body. Originally, I thought it might be the gaskets. I installed all three new gaskets and the problem persited. I put it on an engine stand this afternoon, and noticed raw fuel was pouring out from the back plate and the throttle body as soon as the engine started to run. 

Is there any chances I can put something backwards that can cause the problem?

Thanks in advance for your help.
