  1. OK, let me throw this into the mix, shoot me down if you will: The “skis” that the “goat” appears to be standing on, with closer inspection, look more like this Bedford badge. I am sure somebody will put me right but that doesn’t look like a Bedford lorry to me, so maybe it is there for another reason? Bedfordshire & Hertfordshire Regiment, maybe? Consider also the “goat”. Perhaps not a goat, but instead a crudely executed version of the animal from the B&H cap badge?
  2. “Self appointed Field Marshal”. I like it! 😀
  3. Well, it has been a long time but I am happy to report that the tank is fixed. The worse end responded well to the molasses bath and the slightly better end cleaned up with a wire brush and some Jenolite. Predictably, once all of the rust was out of the way the damage turned out to be worse that it at first appeared and it was necessary to make a small patch for the worst bit. Being new to this soldering lark, a bit of trial & error ensued but after an hour or so I got the hang of it and managed to get all the holes filled. I don’t have the facilities to pressure test, so the tank was supported on trestles and filled with 20 gallons of water, with the intention of leaving it for a week to check for any signs of leakage. Then lockdown intervened...... I am happy to say that, after six weeks it hasn’t leaked a drop, so the tank will shortly be back in service. Thank you to everybody for your advice; just to recap for the benefit of anybody else contemplating a soldered repair to a fuel tank: 1) SAFETY FIRST: an empty petrol tank is a bomb waiting to go off, unless you thoroughly purge it of all traces of residual fuel. I used a pressure washer, with detergent, at around 160 Celsius for three quarters of an hour. IF IN DOUBT, LEAVE IT TO THE PROFESSIONALS! 2) Re-iterating what Rick said, everything must be spotlessly clean and free of every last trace of dirt & rust if you are to have a chance of success. 3) Use plenty of flux and take care not to overheat the metal you are trying to repair. I used a blowtorch but I can see how a large soldering iron could be better in this respect. Good luck, Andy
  4. Banister’s: https://www.milweb.net/go/banister/ I have always found them very helpful and are the “go to” people for all things B series.
  5. It is very unlikely to be a timing issue causing the problems you describe, especially if it was previously running well. Might be worth replacing the condenser -a nice spark in the open air doesn’t always equate to the same thing under compression. Likewise, wet plugs do not rule out a fuelling issue; too rich a mixture (maybe due to leaky float valve or stuck float) might cause the symptoms you describe. Also, always a good idea to check that the silencer isn’t blocked with carbon deposits. First though, there’s a very simple test to narrow the cause down before you do anything else: Drain the carburettor and turn the fuel off. Then, with the throttle wide open, give it a generous squirt of Easy Start. Try to start it: if it runs any better on Easy Start, you have a fuelling issue. If it is no better, look at ignition or, as you suggested, crankcase seals.
  6. Having experienced a steep learning curve myself with RR B series engines over the last couple of years (and benefitted from some excellent advice via this forum), may I suggest the following: 1. Get ALL the plugs out and replace (or at least make sure they are thoroughly clean). 2. Replace the carburettor diaphragms as a matter of course. They are the devil’s own invention and you would not believe how badly these engines run when the diaphragms are not in tip-top condition. It would not surprise me if this turned out to be the whole and entire source of the problem. 3. Replace condensor(s). Other things to consider: Were the points correctly set up with a dwell meter when they were changed? You are probably best off leaving the ignition timing alone; if incorrect it might cause loss of power but is unlikely to be causing such profound symptoms as you describe. Good luck Andy

    Where is this?

    “Abandoned Military Vehicle Graveyard” “Army Base” my @rse. The variety of vehicles along with the presence of the clearly fake WW1 tank, suggest a storage facility for a company supplying vehicles for film/TV props. That little toe rag deserves a hefty kick up the backside for his trespassing; I admire the owner’s restraint in his response on YouTube: ”Hey guys, nice video. Next time you want to look round my yard and vehicles drop me a line and I’ll show you the rest of the toys” 😆
  8. Is it part of a rifle stowage from some kind of armoured vehicle?
  9. Something is out of kilter then; I’m Staff Sergeant with 252 posts but Johann is Lance Corporal with 448....
  10. Purely out of curiosity, can anybody explain how “promotion” works on this forum? It doesn’t seem entirely fair to me that “Johann”, with 400+ posts, an impressive collection of MV’s and one of the bravest and most interesting projects we have seen, should remain a Lance Corporal....
  11. Yup, visited that one. Whilst being respectful of the memorial and refraining from clambering over the tank, it was difficult to see what had knocked it out; no sign of armour penetration. Then I noticed the damage to the right front suspension and the upward deformation and failure of the sponson base; my immediate thoughts that it had run over a mine were subsequently confirmed.
  12. May I join the previous members in paying tribute to your skill, patience and attention to detail? A fantastic project and a fascinating thread. Thank you.
  13. A nice vehicle with interesting history but can anybody see that making more than scrap value in the current circumstances? Not unless there are a lot of a very brave and determined collectors of of specialist vehicles out there, IMHO. I wonder how they arrived at the £3000-£6000 estimate?
  14. My first thought precisely!
  15. I have to agree that they are not the easiest engines to work on; having struggled to set the valve clearances on a B80 installed in a fire engine, the mind boggles at the the magnitude of the same task in the confines of a Saracen or FV432. I think I would have been extremely tempted to leave them a little slack and only touch them when the engine came out for overhaul....
