Change the sockets before you fly again. It will take you about 10-15 minutes and could save you the propeller and maybee your plane. I see that you are flying a Kolb Mark II, a pusher so anything that gets lose on the engine will hit the prop. It is a money well saved to install the new sockets asap. Just a friendly advise.

Yes I would change the sockets. It is not likly that they will fail and let the carb fall off but if the cracks go right through then you will suffer a very lean fuel supply to the engine . This at best will result in over heating ,and could result in a seized engine. I have removed the sockets and checked to see if the cracks are showing on the inside and made a judgment call from that check to fly the plane but only until the new parts arrived. I believe it is the sun that makes these crack as they only crack from the outside in . I have never found any that were cracked on the inside with no cracks on the outside.

Cracks only get worse, and you can't visually tell how much time you have left. Same thing goes for tires, hoses, etc. It,s called "checking", or dry rot. I think ozone does it. The Lockwood book should give the change schedule for it. Bill Sullivan > [b] Bill, I don't have a book on Rotax engines. I downloaded a pdf Rotax maintenance manual from somewhere and all it says about it is to change it every five years or as required by condition. It's that "by condition" that I was unsure of. It looks like most opinions are toward changing it out however so I will do that.

Change them out. It's cheap insurance for you and your plane. Don't be one of these guys that try to salvage every penny out of their plane. You will pay for that in some way some day. The book says replace them. Replacing them will give you piece of mind and safety. Why throw the dice on what someone told you with your safety and your wallet when you are already questioning the advice yourself and the book tells you to replace the carb sockets. The carb sockets are one of the inspection items. Fly safe, fly smart. Take care. -------- Roger Lee Tucson, Az.

I downloaded a pdf Rotax maintenance manual from somewhere and all it says about it is to change it every five years or as required by condition. It's that "by condition" that I was unsure of. Seeing some good/bad pictures in the manual would be nice. But I guess when they say cracks they mean any cracks, small or large. The guy who gave me the advice to keep it on longer has built many experimental airplanes and has lots of flying experience with experimentals. His business card also says "Cuyuna & Rotax repair station" so I had no reason to question his "expertise" until this other guy came along and told me to change it out. That's when I began to question. Anyways...I will be changing them. Thanks to all for the advice. -------- Cristal Waters Mark II Twinstar Read this topic online here: http://forums.matronics.com/viewtopic.php?p 5933#205933 ________________________________ Message 7 _____________________________________ Time: 09:15:10 AM PST US From: "Noel Loveys" Subject: RE: RotaxEngines-List: Re: carb socket replacement One word missing from the business card...

It gets awfully quiet when a carb socket breaks. (Sometimes only somewhat quieter, but a 503 running on one cylinder doesn't put out much horsepower.) Since some of the locals have broken carb sockets in high-g maneuvers I have decided to replace mine every few years regardless of appearance. (Currently 250 hours and they look new.)

You should check the calibration on your torque wrench every year or if you use it as seldom as I do now check it each time you use it. When you are finished using The torque wrench remember to reset spring type wrenches back to 0 to take pressure off the spring. Never use the torque wrench to loosen nuts or bolts. To check the torque on a nut or bolt you first must slacken the nut or bolt. Finally Snap-On makes a real nifty, and expen$ive, digital torque wrench that calibrates itself before each use. It has both an audible and vibration notification that the pre set torque has been achieved. The wonder of the load cell!
