I am using the Whirlwind prop that came with my FWF kit from Arion.Curious as to what pitch other folks with this prop are using and what they are getting for IAS.  I have my prop set at 14.5 degrees and am seeing about 75 mph at 2850 rpm.  WOT gives about 3000 to 3050 rpm.The 14.5 degrees was selected to get greater than 3000 rpm during break in as recommended by Jabiru.See More

Exhaust stack to muffler leakage

During a pre-flight inspection I noticed what appeared to be exhaust stain on the inside of the cowling.  It looked to be adjacent to where the 3 left exhaust stacks plug into the muffler.Right side does not show any stain.Stacks are fully inserted into the muffler up to the welded-on stop.  No obvious cracks or holes in the muffler.Has anyone else experienced exhaust leakage in this area?  If so how to fix as there are no gaskets at this joint?Thank you.Grant Ziebell See More
