Buly,
Are you rich enough ??

When I cold start, I turn the mixture to 3 o'clock,
cold start on, bump the prime twice, and hit the
starter.

Even after sitting for a month or more, it fires up
after about 2-3 seconds of cranking.

If I don't have the mixture turned to rich, or the
cold start on though, it won't fire.

Steve, I have cut off switches on my pumps and I
shut the engine by
shutting the fuel pumps off. The strange thing is
that once it
sputters, I have to give it a boost with the cold
start, or it will
die again? Maybe I have to install the bypass fuel
bleed circuit? all
my injectors are uphill and any fuel leaking, will
go in the engine.

Buly,

I have the opposite problem.  When hot,, mine

start

somewhat hard.  Especially if it has sat for a

while

and has a good heat soak.  I believe that my

intake

gets hot, and is what causes my hard start when

hot.

On your problem, I used to have an issue with cold
start, before I added a cutoff switch for the

primary

FI pump.  I had trouble leaving pressure on the

fuel

rail, because it seeped through the injectors and

ran

out of the throttle body.  Some ran into the

engine

also, which caused it to be flooded.  Wet plugs

are

hard to get started.

On shut down, I turn off the primary FI pump, and

let

the engine die before cutting off the master

switch.

No more problem with the flooding.  Also, if I do
flood it (hot start), I shut off the fuel pumps,

and

when the engine fires up, I flip the pump on and

the

engine continues running.


FWIW,
Steve Brooks


If your problem is flooding, I can see why priming
doesn't help.

Today I did couple of fast taxis with my test

pilot

that flew the
plane the first time with the turbo and fixed

pitch

prop.
We had 500 pounds on the front seat and the plane
lifted off the
runway in less then 1500 ft. He said it is a

great

improvement from V.
1.0. That's the good part. Last few times I had
trouble starting
cold. If I give it a sniff of the starting fluid

it

will sputter and
I have to turn on the Cold Start for a second or

two

to get it going.
Before start I hit the primer 4-6 times, but it

does

not help. After
it worms up, starts instantly. Anybody with ideas

to

improve the
situation? Thanks.
