QUESTION: My Lycoming IO-360-B1E engine will be majored sometime early next year and I am trying to educate myself. The facility I plan to use for the overhaul says that a reground cam is just as good as a new one. Could you please explain how a cam is reground. I don’t understand how if it is reground that you still have the original lift and duration, etc.

QUESTION: I’m operating a C-172 with a Lycoming O-360 engine at an approximately sea level airport. Is it normal to have to lean the mixture for ground operations and takeoffs? I have to or the engine runs a bit rough. Perhaps the mixture settings on the carb are not adjusted correctly, although some say it is normal to lean even at sea level. Should one use continuous carb heat for landing? Some people say it’s not necessary.

QUESTION: First, let me say thanks for your excellent column. It’s always one of the first things I flip to when GANews arrives. In my 1947 PA-12 (I’m new to the plane, purchased after complete restoration), I have an O290-D2B with about 18 hours on a new limits field overhaul, including new exhaust valves, seats, guides and springs, rings, pistons, lifters, oil pump and gears, inspected and reused crank case, rods, crankshaft and camshaft. I have installed a spin-on oil filter kit and my crankcase vent/breather line runs below the cylinders.

QUESTION: I have a Glasair, started by someone else, with an IO-320 engine. He has a fuel return line from the side of the throttle body going back to the bottom of the header tank. It is my understanding that there is not supposed to be a fuel return line on this system.

Mixture lever positioning after idle cutoff
February 11, 2005 by Leave a Comment
QUESTION: I operate a IO-540C4-B5 in an experimental. I am wondering about the correct position of the mixture lever after idle cutoff has been selected. Should I leave the lever in that position, or should I advance it (after the ignition is switched off) to full rich? Is there any benefit to the internals of the servo to leave the lever in one position or another from flight to flight?
