Inliners International Forums General Discussion Engines PCV Retrofit to a 235

You have to access the idle feed restriction,easy on some carbs,near impossible on others.On some situations ,a switch to a carb know for the same engine but had an original PCV might be the answer.
I think a proper PCV sustem is worth the trouble,more likely to get rid of internal water vapor and maybe even more important,1/2 the pollution of an older engine comes from the road draft tube.
