I have an RV-6, O-360, 850 hours, built it 2000.
On take off and climb out the other day it felt a bit low on power. As I was climbing I started leaning it a little and the power came up. It felt like I was at a high altitude airport or like the carb heat was on. It has not normally required leaning like this before. I am basically as seal level and 70-80 degrees. Something seems to have changed. I checked to make sure the carb heat door is fully closed and it is. I checked the idle mixture (which understand does not really effect full throttle) and I got a 20-30 rpm rise right before shutoff idling at 1000 rpm.
This is the original carb and I have not touched it since I purchased the plane. Been running fine. Is it time for a carb overhaul? Could the float be causing a problem. I know very little about the internals of the carb but I can always learn.
Any suggestions on where to start troubleshooting?
