Update:  I've also had problems crop up with the needle valve leaking butane
when open.  A woomph and a cloud of flame.  Tried a couple strategies but the
only one to work was requesting a few new O-rings.  I received three and
a new needle-valve (w/O-ring).  Popped the new one in and it was all good.
I measure the O-ring at 4.5mm in diameter with an inner hole of perhaps 2.5mm
with a wall thickness of about 1mm.  I suggested to the maker that two O-rings
on the needle valve would be a good idea.  Extra O-rings for every buyer would
be good for a start.

Thanks for the tips Wayne, I'd like to get one of these some day.

Might be your lucky day's a coming. It looks like Gill has a couple boxed up for cabin fever.

Sound complicated!  That said, great looking little engine :-)

But where's the video?

For what it is worth....

  I received a Rider Ericsson R01 pumping engine for Christmas.
The purchase was at the 'sale' price of $199 plus beaucoup $$$
for shipping.  It is a nice looking engine and, once I got the
hang of lighting it and keeping it lit at a modest flame, it
ran well.  Fast, even.  I tried the priming to no avail.  Worst
of all was trying to get the little primer cap screwed back into
the priming cup while it is running.  It made me feel very clumsy.
I did try a bit of steam oil and it started pumping but that is
cheating.

  So, with it running, I used a hypodermic needle with silicone
tubing at the end to fill (and keep filling) the primer cup.  When
water started to pump through, instead of trying to get that tiny
cap threaded into the primer cup I took a bit of the silicone tubing
(with one end flame sealed) and stuck it on the priming cup.  VERRRRRY
easy.  That is my trick and advice.  Works for me.  I added several pics.

Good Luck,
Wayne
