Losing fuel effiency

I have Saito FA82 in my UCD. It has recently been running for less time per tank. I think it may be losing power also. Initially I would get 10min now I am down to around 8 with a full tank.

I use Omega 15% fuel and it is using a 15x4w prop. The engine is inverted.

Ideas?

TIA

RE: Losing fuel effiency

Your engine is richening up, resulting in the lesser flight times, and the loss of power.
It could be the the low speed needle, or even the high speed is moving and changing
due to vibration. ;)

FBD. :D

Assuming you are tuning it the same way as you were earlier, it may be time to check the tappet clearances, if you haven't done so already.
