Hey guys- I have a 70 c-10 with a 250. I ve been having trouble getting the engine to run right- but a buddy told me about a whistle that the carb will emit when it is running right- anyone ever heard of this?
I beleive that "Whistle" is air flow through the venturi's. It could be a vacuum leak too. If your carb has a nice flow rating, it will whistle while your working it!
