During run up, carb heat check shows a very small drop on RPM, (maybe 10-30rpm), and no other noticeable engine data indications such as a change in EGT, fuel flow, etc. You can almost not tell when it's on. I don't have a carb temp gauge in the plane.
Looking at our setup (pic below. bought, not built) I'm wondering if this is typical or if we should add a little baffle material to the flap there, or make a larger flap to get a more complete seal on the main air intake and force it to take more hot air from the engine bay for the carb heat. Concern would of course be blocking too much air from entering...? Any advice here, or examples of what you have is appreciated. Thanks!
