While pulling my carbs off I noticed that each head has an air vent. One was capped off, the other was open.
Where should these go and why are they needed? Will capping these contribute to oil leaks? Here is a pic I found: http://www.914world.com/bbs2/uploads/blog-1...-1131214564.jpg Thanks |

engines that can't breathe don't have all their power freed up AND they leak oil. The pressure will find a way out!
I have a 4Qt stainless steel tank in the works, it'll be VERY nice and slim to fit nicely.. |
