Hi Cristal.
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.

Hello Cristal . 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.

[quote="williamtsullivan(at)att.n"]Cristal- Change them. 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, 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.
Thank you.

Hi Cristal,
Downunder and Johann, have very sound advice. 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, 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.
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.

Two questions:
1. How much are the carb sockets?
2. How much is your plane worth. (Time AND materials.)
Do you get my point? 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.)

Sure did. Turns out my old torque wrench was about 15 inlbs off. Torqued the
head with a new one and it woiks poifect. Now all I have to do is pull the
head off & retorque the cylinders & check all the misc other bolts. Fun fun!

A few ideas on using the torque wrench.
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!
