I spent the first part of tonight doing some maintenance to my hangar entrance. The previous tenant was nice enough to put some asphalt over the rails the sliding doors ride on. The outermost strip of asphalt was in pretty bad shape, missing multiple pieces and causing some slight difficulty in getting the airplane in and out of the hangar. After about 30 minutes of work, everything is fixed for another 10 years.

The real purpose of coming to the hangar tonight besides manual labor was to install the new "No Leak" intake modification Ross Farnham as SDS (www.sdsefi.com invented. While I didn't have a leak, much like many other builders, I never liked the intake sealing method which came with my engine. The paper gaskets would dry out and rot, and the tubes used to connect the intake tube to the sump would dryrot. Ross came up with a brilliant solution to both of those problems. I ordered the kit last Thursday, and 6 days later it arrived. The kit is very complete and includes everything in this picture.

This is how the factory intake tube works. The intake tube sits even with the top of the intake pipe flange. A gasket is the sealing mechanism between the intake pipe and the cylinder.

SDS's flange has a deeper depression, causing the intake tube to sit slightly lower.

A silicon o-ring get installed.

Next a metal ring is placed on the inside of the o-ring.

The metal ring gets pushed down and the gasket is held into place.

A bad pic of one intake tube installed. The constant tension clamps and silicon intake tubes are a really nice touch. Not only does it look better than the factory pipe clamps, it also is one less maintenance item to worry about. Furthermore, because it provided a constant force around the whole pipe, you don't have to worry about any leaking of air in that pesky flat spot where the adjustment screw is.
