Last month I bought a combo from Chief Aircraft that contained the BME-115, a pair of stock mufflers and an AM Yak-54 35%. What a great looking engine, I'm looking forward to hearing it run.

The carb has the 2 needles, how can I tell if it is a modified carb?

Also the tunnel in the left muffler does not line up with the needle valves on the carburetor. The block between the engine case and the carb measures 1 ½” which puts the needles almost ¾” too low so that the needles cannot be adjusted through the tunnel. Is this the right block installed?

I too have tried to contact BME by phone, fax and email but no response.
