  1. I've had a couple go that way and also one of my saws, they were very well used but had been reliable and I put it down to a combination of worn or hard crank seals and cold weather... once I'd managed to get them running and warmed up they would then start normally, so that could be a possibility in yours. I used to put them next to the stove and warm them up in cold weather and this usually worked but if not a wee squirt of fuel down the plug hole would do the trick.
  2. Hi, I have to do this with one of my saws occasionally which can result in me flooding it, at which point I either walk away and leave it for a while or pull it over repeatedly with the throttle tapped fully open and the choke off which eventually clears it. If you suspect flooding then you could also take out the plug and pull it over a few times and that should do the same job. All engines are slightly different in their idiosyncrasies as said, if it gradually splutters back to life as above that could indicate flooding, good luck.
  3. Aye, for sure to all of that.. although it would seem that these RCV engines have solved the sealing issues due to modern materials science and precision.. perhaps if these issues had been addressed sooner we might not be in IC engine place that we are today. Also I recently watched something on the storage of energy in very large flywheels powered using Stirling engines. Personally. the latest drive for all of everything to be electric I've nothing against but I CAN see it for what it is and that EV's aren't greener at all when you take into account manufacturing and end of life... there just polluting in a different way, and for the foreseeable future I don't expect much other than cars / bikes etc to be EV... Quarrying, shipping, flight diggers and everything else will still be diesel... but if they were twice as efficient that would help. However if we had access to Tesla's secrets for instance which I firmly believe are being concealed then that would be the real game changer that the current cabal are resisting, I read that OPEC were meeting today to decide what Price per barrel to inflict on us next. ๐Ÿ‘
  4. Yeah, I'm no expert on aero but I know that many of the radial engines were sleeve valve running off a cam at bottom of the sleeve. To me tech has finally caught up with the concepts of 100 + years ago and is enabling some of these excellent ideas to actually work, I think that the main advantage is due to comp ratios of 16 :1 being possible without detonation thus more completely using the calories available and therefore much more power and massively reducing pollution.... I think we're way past the time that poppet valves should have been dropped [ no pun intended ] ๐Ÿ˜ Apart from anything else, and although it's much improved since I was young, more complete usage of the available calorific value would mean much smaller engines to do the same job. This has fascinated me since I read about the Aspen engines in Motor cycle mechanics in the early 70's, cheers.
  5. I am not up to date with these RCV's but I think they were initially developed for model aeroplanes. The concept goes right back to the start of engine development with many different rotary valve designs many of which were dropped due to lack of engineering tolerances and sealing issues, there's an old book titled ' Valve mechanisms for high speed engines ' by P Smith which had many different designs illustrated. Back in the 40's there was an English guy Frank Aspen who experimented with rotary valved Velocette's and got great performance with very high compression ratios but could never get the sealing problem to be reliable and they burnt too much oil.
  6. If you like that solution you'll like this one as well and it's much simpler, I posted this a few years ago on here but got no replies... sorry it's not a Husky ๐Ÿ™„ At the time they were looking for a partner in the forest / garden machinery sector to help with develop their chainsaw / strimmer engine which then was 35cc, it seems as they found one, cheers.

  7. I think you'd probably be ok to take down as they're quite small and I'd expect the roots not to rot that quickly giving you time to monitor and possibly under pin if required.... imo
  8. I'd say these days they are or the flue is backfilled with insulating material like vermiculite for instance. Doesn't seem right.. but I'm no expert on my stove the outer skin is often too hot to touch and in fact requires 2" clearance in passing through floors or roof, I think your best bet would be get your flue inspected by a professional to make sure it's safe ๐Ÿ‘
  9. Yep, I don't think I could name a single Labour politician any more and now that I think of it tbo the same applies to the SNP up here. apart from the Kranky cnut of course. I wonder if this disconnect from politics in general that I have due to a lifetime of listening to their shite and observing their corruption, stupidity and pocket lining is also common enough in other folk globally. and to a large extent this absence of oversight has led to the ability of these halfwits to rise up into positions of power that they don't deserve making decisions that we're unaware of but that affect us all... or perhaps this has always been the case particularly, when you look back into human history ! And it seems now that the upshot of this intellectual dearth and the absence of morals in favour of greed and personal agenda's in politics has allowed big tech / pharma to a position where they now have the technical ability and power to enable them to pounce on the whole of humanity completely unchecked.. only my opinion, most will probably disagree.
  10. Hi, page 41 mentions the PPR briefly but then tells you to contact your dealer for the setting...cheers. https://stephensonequipment.com/wp-content/uploads/2016/10/Bandit-90XP-150XP-200XP.pdf
  11. Yeah Stubby I totally agree with you about that I don't listen to so much blues any more, the early 70's was my time and although I sometimes listen back to my old favourites I kinda like it better now when I find a young artist that I've never heard of doing their version of stuff I was into back then. I just checked and this was released in 1994 on an album of the same name.. think I might buy it ๐Ÿ‘ Now that you mention it I hear Dave Gilmour as well... and I've been in a room that was a studio๐Ÿ˜ Can't find the 1994 album but bluest blues is on Keep on rockin released in 2010
  12. Thought this was very good ..... it's just three folk in a room but ๐Ÿ‘ hope someone likes it..
  13. Up here in the north west more wasps this year than I've ever seen before, trying to work in the shed with a byke in the rafters became impossible.. had to smoke them out with a smokie fire in a digger bucket.. shed now stinks๐Ÿ˜ General observations from this year around here are.... Bats, not as many as in the past but still around Moths, next to none. Butterflies, more than usual, species and numbers. Bees, same as above Midges, started bad but ended up tolerable... if that's possible ! Fresh run Salmon, zero. I think that bugs on your windscreen or visor is a pretty good gauge of insect populations abundance and compared to my youth there's no comparison. I'd have to say that in my life moths and wild salmon are the most noticeable casualties but I sure know that there are many others and it's interesting to hear what folk notice in different parts of our small island๐Ÿ‘
  14. One of my favourites
  15. Must depend where you live, up here it's Rowan that gets tagged with this ๐Ÿ‘ Got Alder everywhere, very fast growing...
  16. Hi, I've been thinking about a 1/2 ton tracked dumper for a while now but hadn't even thought about an electric one, but certainly food for thought though ๐Ÿ‘ The one you put the link to seems to be the same as the Lumag for the most part except for the hopper and as the price quoted seems to be inc. vat would it appear to be a bit of a bargain [ after just a quick look ] cheers.

  17. Reading this thread I have to pinch myself .. to think that a simple engineering job like that should be in any way difficult or expensive to have done blows my mind as in just how far we've sunk in this country that previously led the world in engineering. I know that in Glasgow where I served my time 50 years ago I would now have equal difficulties in trying to get a job like this done as most of the jobbing machine shops are gone. However it is heartening that there are people on here able and willing to help.... I'm sure you'll get it made, good luck.
  18. Dead mice are tastier than Mcd's.. I saw it on ' Naked and afraid ..๐Ÿ˜
  19. I bet you it's still better that than most of the crap that's produced to do the same job today ๐Ÿ‘

  22. Ok so your calling me a liar then, that's fine by me.... you've certainly got the knack of twisting others words, I recon you're just bored at work and need someone else to take the piss out of because you like arguing... all over a news article that happened before you were even born, get a grip mate๐Ÿ‘
  23. But there's a plethora of info on poisoning from home distilling... I don't really know what it is your trying to disagree about...it's not like I'm making this up.
  24. I really don't see what point you're trying to make unless it's just that you want a laugh... which is fine by me ๐Ÿ‘ But if you'd like to discover the origin of the term ' blind drunk ' then this article is one of many that explain the effects of methanol poisoning, cheers.

  25. Ok, but I distinctly remember this incident being news headlines when I was an apprentice...papers and telly, others must remember this, they distilled and drank wood alcohol is what was reported. I'd guess '72 or 3.. but... ..as I just googled it several ways with no result I must be mistaken .. I'd only give it a few years before a google search of WW2 will turn up empty, cheers.
