I'm currently installing a BME 102 and I have a question about the carb. I've used 3W engines in the past and always had to install a brass tube to the hole in the metal plate that covers the pump on the Walbro carb and then run a piece of fuel tubing from the plate to inside the fuse of the plane to make the engine run good while in flight. I noticed that the plate on the carb of the 102 has 3 holes in it and I would like to know if BME engines need the same modification done to the carb as the 3W engines.

Any help you guys can give me would be greatly appreciated.

some do and some dont its all about how the air is hitting it for your airframe.
