Leipzig in November, that's brave! Where are you heading to? cold headwinds are not fun, are they? I don't mind rain or even snow, I just hate cold headwind. Good thing you have sunny days. Anyway, keep up the good spirit, we're here to support you!
(I wish I was on my saddle too right now!).
Sorry to hear about your pump, I hate to have these kind of problems on the orad. I have been using the whisperlite for several years and I never had any probelms with it (so far so good) - just the regular maintenance stuff. But now that you mentioned it, It reminds me that Friedel from travellingtwo pointed that specific issue when she did the review of the Primus Omnifuel. I quote: "As soon as you pick up this stove (the Primus Omnifuel), you realise the quality construction. The pump is made of metal, with a leather plunger on the inside (compared to plastic and rubber for the MSR Whisperlite). It feels extremely robust. We have no doubt that it would stand up to a lot of wear and tear."
Anyway, what are you going to do to get that fixed? good luck to you...
