1. What do we like for Yak-52 tire pressures? 40 nose, 45 mains? 42
all around?
2. Regarding that Yak-52 header tank vent mentioned earlier. So, if
obstructed, that can cause leaning... if so, would or wouldn't the
fuel pressure be lower than nominal? Would this cause elevated CHT?
Finally (not being near the plane), where is this vent? I'm assuming
under the fuselage forward of the header tank? If it is blocked, how
do you test this? Unlike the wing tanks, you can't pressurize the
vents and listen to the filler holes. Suggestions?
Thanks in advance for input... -Eric

The Yak 52 header tank vent line is tied into the main vent line which is below the fuselage. There is no separate, overboard vent line for the Yak 52 header tank. See attached drawing.
