FYI

The carb modification to the BME did not work as expected. Preliminary running seemed good, but after a few laps around,the engine quit on a throttle up from a low pass. Subsiquent tries accomplished the same result. End result was that the tube connecting the pump side to the intake airflow did not have the same effect as on my G-62. After removing the joining tube, the engine ran better, but kept quitting from fuel starvation (no fuel in the line). I can only assume that the upset in air balance must have bent the little tiller arm that controls the main flow needle. It was not opening at all or very little because the engine would only run on the choke, then quit.
At that point I brought it home and took the carb off, removed the adjustable needles, flow control needle ect...I do not have a solid definition or position as to where the flow needle should be, except that my experience has provided me with a working feel for it. I do believe there is a measurement, perhaps someone else can enlighten us all??

End of story, the intake manifold tube is still on, I installed a baffle in front of it to divert direct turbulance. The pump side has a nipple soldered to it with a very short lenght of fuel line formed in a "U" to prevent disturbance there. Everything is back together and it again runs extremely well on the ground, it will be next weekend before I can try it again.
