RE: Throttlability of 1/2A Cox (and Norvel too) engines
AndyW, once again, thanks for sharing your wealth of info. BTW, how would you rig up an adjustable air screw on my carb? As to your question, yes my AERO/AME carb is of the round body design but I just don't see where a bleed screw can be put in as the carb body itself is only slightly larger than the venturi opening. The carb does not have a nice square body with a step for positioning the bleed screw like some of the carbs in the pics posted in this thread.
Also, thank you for the articles but unfortunately I cannot read them...the print is too small when I click on them. Is there a way to obtain copies of them or at least be able to read the text somewhere?
