So, in the service manual, it says too, install the flame arrestor to the left cylinder head cover. That connection starts at the air cleaner, correct?Then it says to install the Crank case ventilator valve in tappet cover and connect hose to valve and tube to fitting in manifold. If that is all correct do I just plug off the fitting coming out of the intake manifold? The fitting has always been there and I don’t claim its even there for a reason or am I missing something and its for something? Bye the way, thank you for all the assistance.
