The P.O. put one of those K&N breather filters directly on the crankcase "stub", it became almost fully plugged and my cruiser was running like crap. I pulled the filter off and now it runs alot better. My cruiser has been crudely desmogged but it has ran very good in the past. I use it for plowing, which it has gotten alot of use this year, just around my property. It has not been ran wide open in a while. I am wondering if this breather should have a small hose on it first, becuz with the current filter setup it just runs right back in their (make sense?). I thought I should run a hose maybe a foot or so, so it makes a loop and then the filter? Did a search and got a lot about diesels. Just a regular 76 2F. Any help would be appreciated, and pictures too. Thanks everyone.
