OK--here goes my first post. I have been flying and building for years but brand new on the gas conversions. I know some of the questions are probably answered here but could not find them. I have a weedwacker Homelite 30 cc. I hope to put it on a plane that is now 9 lbs with everything on it but this engine. It has a front plate behind the flywheel that is part of the lower case that holds the mag. # 1 Do most folks mill this plate off to lessen the weight if they are going CH-Ignition? When I pulled it down,the back plate that went into the crankcase was part of the plastic housing. #2 Can I make a cup type mount that will replace this and if I can will I need to make this with a plug that will go in the same depth that the plastic one was to keep the same case pressure or case atmospherics? Also What is the best model Walbro that would work on this engine? The venturi just don't look as big as the ones flying at my field. Any help or pointing me toward the right URL would help. I can upload a photo if it would help and thanks to the ones that has Probably seen these same questions a hundred times. ha. ha. Hooker53
