new sprag clutch.

  HI All,  I just had a new sprag clutch installed on my 912 ULS, re installed the engine and found that it is very hard to hand prop compared to before the  new sprag clutch was installed. Is this normal that a new sprag would make it so much harder to hand prop ? I mean its like twice as hard as when the old clutch was in. Any comments I would really appreciate, I am wondering if things may not have been installed right. Thanks for any opinions and help. Ron J.See More

UL Service

In August of 2011 I did a UAV job for the ARMY with a new Rotax 914. From the start the engine ran poorly. After long hours of diagnosis it was found that the magnets on the flywheel were not in Rotax speck. Rotax required us to purchase a new flywheel (700.00$) and send the original one in for credit if they determined it to be faulty. The new part fixed the engine. They accepted it back and sent me a warranty clam form. After several calls to Dean at Lockwood Aviation and three years I still…See More
