| Subject: | Lycoming Engine Fuel Flow Problem... |
Dear Listers,
I flew the RV-6 tonight that has a 1660 hour Lycoming O-360A1A with a Hartzell
CS prop. I flew it 7 hours over a 3-day period about a week and a half ago with
no issues whatsoever. Tonight, on take off, the EGT's all climbed into the
1450's right after take off and the CHT's were in the 400-450 range. The mixture
was full rich. The engine didn't seem to be underpowered or rough but the
fuel flow was about 9-10 GPH when it should have been in the 17-19GPH range.
On the downwind I tried fiddling with the mixture with no change in making it
richer. The mixture did make it leaner. I switched from the right to the left
fuel tanks with no change. I have two fuel flow transducers one feeding the
Skyview and the other feeding a Matronics FuelChec DX. Both were reading similarly
low fuel flows at full throttle - 9-10gph. I didn't think to flip on
the electric boost pump. But the flow definitely seemed restricted. The mixture
control seems to have normal throw in and out and isn't binding and does
lean the engine. I came in and landed with no issues.
I haven't pulled the cowling yet to have a look to see if its something obvious
with the mixture cable, but what are some thoughts on what this could be?
Mechanical Fuel Pump?
Something in the Carb?
Plugged fuel line?
??
Thanks for your feedback,
Matt
