YS 140L not starting

[Gerald Gallagher]

First remove or do NOT put glow starter on eng. Open needle valve till
it almost falls out, open throttle to full throttle, spin eng about 10
sec with starter, close throttle & reset needle to correct setting,
Start normally. VEROOMMMMMM
works for me! Good Luck.

Check valve in backwards by chance?
Fuel filter plugged? 
Might have a pressure regulator sticking. My engine will sometimes be
tough to start after it has set a while (3-4 days).
Changing out the diaphram, plunger and valve seat may be a cheap easy
thing for you to do and eliminate the possibility of fuel pump problems.
I ordered several sets of spare pump parts from Central, they are only
about $6 for plunger, valve seat, diaphram, and gasket. But you did say
it just came back from YS, maybe something is just sticking preventing
the engine from getting fuel.
 In my similar situation, theYS gurus I fly with had me open the
throttle up wide open and turn the engine over with the starter for
about 10 seconds and then try to start the engine. Even then sometimes
it might take 30+ seconds on the starter before the pressure regulator
would pickup and it would hit. If I fly daily it starts right up. 
I think that what is most likely going on with mine is something in the
fuel pump is sticking if it sets up. Mine is running fine as long as I
continue to fly everyday, but I have the parts on hand now if it quits
again on me. 
 This may be old news to ya, maybe it will be useful.

It’s not getting any fuel. 

 

Try blowing into the fuel line that goes to the high speed needle
assembly. You should be able to blow through it. Make sure needle is 1 ¾
to 2 turns out.

Engine doesn't want to fire. Symptoms: 

Fuel draw not the best, very little pressure in the tank, compression
seems OK.  When we first pulled the cowl the fuel was to the filter
which was the high spot in the line, after some fidgeting (not sure why)
the fuel line had visible fuel to the engine.  

Removed the glow plug, put a few drops of fuel in the cylinder still
basically wouldn't fire.  There we a couple of very minor puts while
turning with the starter after putting the fuel drops in the cylinder.
Pulled valve cover, valve gap not the problem.  Glow plug glows, check
valve is in the correct direction.  If you put your finger over the pipe
exhaust can't feel any pressure pulses as we turned the engine over.
This engine hasn't been run since comming back from YS (supposedly
rebuilt).
