Re: N275CH First Flight Q200

Thanks for the input. It will help solve your problem.

Some answers to Jim's questions:

Gascolator: NO ******** Good

Heat sleeve: YES ******* Good.

Fuel line between carb and oil tank: NO******* OK where does th
efuel line come though the firewall? Is it the shortest run possible?

Aux tank: NO. Straight from header to carb.******* Filters clean?

Fuel on board: About 15 gallons*******OK

Fuel vent: Checked before and after flight. Not hard plugged but who
knows if fuel plugged it on this flight******* This can definetely
cause the problem you described. It happened to me once. Loss of
fuel flow is no fun. I had filled the main, header and aux tank and
mistakenly flipped the aux switch ON before takeoff, thus putting
fuel overboard via the vent tube. NOT GOOD! Carb heat on and off
contineously let me get it back to the runway.

Flow check header tank in flight position: Not in flight position
but it did flow like a racehorse with the tail on the ground. (I
rechecked this as soon as I got it back to the hangar.)

Actual flow I don't know.************There is a minimum FAA
requirement. Bob F correct me if I'm wrong but I think its 15%
greater than the fuel burn for the engine at full power. ie, 9.5 x
15% or 10.9 per hour (gravity flow with fuel pump off). The facet
pump should deliver about 30 gph to the carburator. This is
typically checked with the tail off, fuselage on the mains and rear
on the floor. You might want to do this check prior to another

Carb Ice: Not Likely at 65 F and dew point about 24F (-4 C on ATIS
before flight).********OK

Heat soak: Now I think that is the question. I did 3 fast taxis with
slow taxis back to the start. Typically, I had done fast taxis back
and forth and I had never seen the oil temp up to 190. I chalked the
higher temp up to the slow taxis and thought it would drop when I
got some air through the engine. I just might have been late and
wrong on that call). Please note it is a long way to the runway and
I was sitting a bit waiting for other aircraft to clear before I was
allowed my fast taxis.*********OK since removing my gascolator I've
been in 100+ weather at OSHKOSH and other places taxiing for
extended time and did not have that problem. It only happened to me
with the gascolator.

Where are you located Kevin?

Congratulations you're still alive to tell the story. Some have
been so lucky.

Do you have a gascolator? Do you have fuel lines running between
carb and oil tank? Do you have heat sleeve over the fuel lines? Do
you have an aux tank? How much fuel did you have on board? Are you
sure your ram air to header was free and clear and not blocked by
fuel or some foreign matter? Was the header fuel flowed at the
in flight position (tail off, fuselage on the mains and split line
the deck)prior to flight? If so what was the flow in gallons per
hour? Could you have had carb ice? Did you allow the engine to
soak prior to flight?

A lot of 0200 engines are much harder to turn over when they are
hot. What you experienced may be normal especially if your temps
very high. Are you around anyone that can verify this condition?

Don't let this mishap deter you. I had a vapor lock at 60 hours
and the engine quit at about 150' off the ground in front of the
tower. I was able to get it around the pattern just as you did
by "pumping the throttle". I discovered the gascolator caused a
lock, I shit canned it and the rest is history.

Hey guys,

Got N275CH off the ground for the first time and got a few other

First engine malfunction

First declared emergency

First time in the dirt (mud)

All this took 60 or so seconds.

The good news is only the airplane and the pilot got muddy.

the runway, hit the throttle and the takeoff went as much per

could expect. Then after about 10 seconds and at about 100 feet
acted like it ran out of gas. Oh shit. I put the nose down,

point was
obviously too short for the job at hand. Hoping for a plan B, I

for a

then started braking. This is where the adrenaline of the

Damn, I
was just
thinking I was going to pull the stunt off. Except for the
all was OK.

Yesterday, and at this point, I am thinking the engine had
hot enough
that fuel was boiling in the carb.

Today, to try to reproduce the problem, I tied the tail down and
ran the
engine until the oil temp was 190 F, the previous day's takeoff
This was when I noticed what may the real problem. After
down, when
I tried to move the prop, it moved with a lot of friction. I
quickly removed
the cowl and the sparkplugs to take away the
compression "resistance" and
found the engine was still hard to turn. Not knowing what to do
lunch was in order. When I got back from lunch, and the engine
and it turned as light as I had known it before.

Any ideas of what might cause this "hot" friction? In any case I
bet an
engine teardown is in my future.
