[QUOTE="_JOE_, post: 1286257, member: 77507"] I was doin a little web surfing today and came across some pics of a Keihin FCR carb with a build-up of dirt under the carb cap. I was shocked at the amount of junk that accumulated under there. The thoery was dirt is being sucked in through the vent lines and then passed into the engine. The dirt was accumulated directly above the choke/hotstart passages. Seeing as how I am extremely anal about maintenance and still have had issues with intake valve tightening I decided to have a look. Holy crap, there it was. A bunch of crud build up. I wish I would have known about this about 60 engine hours earlier. Anybody else see this in thier FCR carb? There is a few options to relieve this issue. Some compaies make a filter kit that the lines plug into. I have also done some digging and found that people are using rc fuel filters with the screen replaced by air filter foam. I think I will be trying this option as I have a couple already and they are only three bucks a pop. [/QUOTE]
