Leaking Carburetor
in General Tech Discussion
8 years ago
Good morning,
A friend with an RV-12 (912ULS engine) said he smelled fuel on his last flight. We removed the cowling and inspected for fuel leaks. We determined that when the engine was running at idle, fuel was dripping out of the left carburetor. It appears that the fuel is dripping out of the top of the float bowl.
The engine has approximately 160 hours on it. It had less than 125 hours on the aircraft when my friend purchased it. It had been flown very little during the 12 months prior to purchase. There is no history of any problems with the carburetors. The floats have been tested twice. I thought they had been replaced but I cannot find the log book entry.
We have not yet removed the carburetor for inspection.
I would appreciate any suggestions on what might be causing the problem. We would like to have a plan of attack before we start.
Thank you for your time.
Bob
