i was checking on my air filter today, and when i pulled the cover off, i noticed two things... first, there is a vacuum hose on the back of the cleaner cover (the part that goes right over the carb, its about 6 inches long, and goes straight down)... anybody know what this line is for?
the second thing i noticed was some kind of oily sludge in the bottom of my filter housing... it was only a little bit, and there was none on the inside or outside of the filter, except where the filter had been sitting in the little puddle...
this sludge was in the bottom of the housing, inside of the filter
any ideas on whats going on in my machine?

Hey fellow Texan, Possible Bad PCV valve. How is your idle? The pcv valve restricts the flow when the intake maniflod vacum is high it's designed to allow excess amounts or blow by gases to flow back thru the crankcase vent tube into the aircleaner housing to be comsumed during combustion. If the valve is bad some oil vapor can be sucked into the housing along with the gases. If you have a rough idle this could also indicate a bad PCV valve by having a vacum leak. Just my $.02 worth.

The little line on the air box on the carb is attached to the manifold, and it works through a bi metalic element mounted in the air box. This is part of the lean/rich condition of the carb based on the air temp coming in. The oil is from a bad PCV valve, replace it.
If you are talking the hose from the carb air box to the manifold, not much really as long as you plug the manifold port. If that port is left open, it will run like heck. When I bought my Sammi, the guy dumped it cause he thought the head was shot. I drove a mile down the road, got out, cut the piece of that hose with the hole in it off with the pocket knife, stuffed it back on the port, and drove away happy.

NCO you are such a bastad ! ) You know you should've driven right back to his house & offered to take your money back !
See , that's why you can't sleep at night now
I always get a little milkshake cold sludge in my PCV line and hoses. I was told it is because my commute is only 3mi and the water vapor in the crankcase doesn't get hot enough to burn off. Is this true? I used to get it in the air cleaner but now have a Megaflow. Jim

Right, I sleep just fine. This was two years ago, and the poor guy had been trying to peddle this thing for over 6 months, and was REALLY wanting it out of his yard. I did him a favor so his grass would grow back in the yard. I still paid $1,400 for it, but it was worth it, Suzi was from California, and someone had moved here and he bought it from them. Suzi has no rust on her which is un-heard of here in the Rust Belt of America.
