Hi All,
Looking for help troubleshooting my Martin Evans' "Conway", 3.5"
gauge narrow gauge 0-4-0.
Tried to steam the loco over the weekend and it raised steam ok to
working pressure (80psi), but when I opened the regulator/throttle, the
steam just whooshed directly up the blast pipe, no power to the
cylinders at all in either direction, tried pushing the loco back and
forth, but no luck.
I have to admit that I did an idiot thing- the smokebox was full of
cinders and ash and my steaming buddy and I took the lazy way out and
tipped the whole engine upright to dump the debris out. I'm thinking
now that this somehow caused one or both valves to become unseated which
resulted in the steam just going straight out the exhaust port. This
loco has outside cylinders with the steam chests inside the frames,
Stephenson gear with the slide/D valves vertical against the port faces.
But I can't imagine the valves coming away that easily, esp. as
they're vertical...
Any suggestions on what steps to take to remedy this, I really hope I
don't have to strip the loco down...
Thanks,
Bede in breezy Brooklyn
