I have a situation with a model.I scratch built an aircoupe earcoupe whatever.In order for the engine to be in correct position for the cowl I turned it on its side and put the tank up as high as it will go.Not high enough I guess.So now it is starving and heating up lean.I have two perry pumps one new in box shakerand one red round pump that works off the engine crank case pressure it has an adjustment on it .I like that idea.
I read the instructions for the shaker and there is so many things you cant do.Its gotta be on the engine a certain way.do the shakers even work or should I try the older pump.This airplane
has been a total pain from the first stick of balsa.Oh well.does any one know anything about pumps.please let me know
