Over propped?
In forward, my engine maxes out at 970 rpm.
In neutral, she revs to the moon and back. 1. pulled the plugs - very sooty and dry. 2. compression test - 120,120,100,120. 3. pulled flame arrester - no change. 3a. choke is open 4. loosened packing gland - no change. 5. pulled exhaust off the manifold - no change. 5a. no loose flakes or obstructions inside the manifold. 6. dumped my old fat butt over the side to inspect the prop - clean with no fouling. This year I changed out the Indigo 10x7 for a Darglo Featherstream 12x7. I knew I'd lose some rpm with the 2 inch extra diameter, but not this much! Suggestions? Rick Bushie
