Kolbers:
I used a piece of "ground" rod to align the landing gear on my MKIIIX. Available
at lumber yard and it is not expensive. Slides right into the opening where
the axles fit. It is strong enough to give good results. Could be used
for grounding a new house electrical system or that of a nice enclosed hangar.
:)
Looking to see every one at Kolb meeting in KY.

Good morning Kolbers,
Has any one flying a 912uls had a problem with Rotax ASB-912-062.
I bought a used 800hr 912uls , and it looks like about every 5 hrs it soots up
both
plugs on only the # 2 cyl. Runs great and has a good mag drop -about a 100 Rpm.
However after about 5 hrs, When doing a cold start the #2 cyl is dead ,starts on
3 cyls
and shakes so bad that it shakes the left carb out of the socket before I can
get it shut down.
If i change out the top #2 cyl plug-everthing is great until the cycle repeats.
I don't think my engine Ser # 5643239 is included in the SB , however the plugs
Are fouled.
As this could cause me to cancel the planed trip to Rock House I really would
like to get this cleared up quickly.
1. As both #2 cyl plugs are involved and all other cyls plugs are ok the
problem may not involve the ignition system?
2. Hav not done a compression check yet . will do one soonest.
3. Only other thing I can think of , I had to cut up and reweld the exhaust,
could be
too much restriction in that one pipe?
Appreciate any Ideas , Don't wont to buy a new head unless I have to.
Frank

If I had that problem, I'd give Ronnie Smith, South Mississippi Light
Aircraft, a call. Ronnie has a lot of experience with 912 engines is a
ROTAX master repair facility.
