YS 140L not starting

[Peter Pennisi]

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).
