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.

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.

Ronnie has a lot of experience with 912 engines is a ROTAX master repair facility.
