Engine Tubing
 
I know that two of the tubes , from the top of the engine and the carb block goes to the breather but, the two that come out of the head, do they connect to each other with a single tube or should they also be open? Sorry this was a question for my 305

The tubes that come out of the head ventilate the intake valve guides to the atmosphere in order to break any vacuum that may exist in them and thus prevent oil from being sucked down into the combustion chamber

The 150's and 305's engine have the same setup.

Thanks for the reply. Does this mean that the two should be tubed separately and allow separate evacuation or should they be tubed together with a single tube. I have seen the latter more often than them being separated. Hope this made since. Thanks again.
