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?
