First rule for weather forecasting - look out of the window. BBC are forecasting loadsa snow north midlands for Thursday night, nothing on the Met office site as yet.

yrs ago we had an old Cortina, drained the tank out and was shocked by how much water was in the fuel about 1/3 by vol. Flying. Wife's a nurse, guy came in looking a bit rough, he explained how he had fueled up him Microlite ready for the next day, but unknown to him his wife couldn't find any petrol for her lawnmower so had syphoned petrol out of his Microlite

Bad day m8 - Sally Ann with be around with some tea for you later:001_tt2:

Well I take great offence - only joking, had enough of everybody being nice:thumbup1: I tend to be a 'rule of thumb' person, with say sawchains tension I think we may all vary a bit about whats correct (adjusted my son's XT660 chain before he went down to the 'Ace cafe' and was told by a copper it was too slack) With the +1k rpm on the Tiny tach, I have adjusted to the book Max but will test again when the saws have been running for say 30 min, so the fuel will be vaporizing better to give me a clearer idea. Either way it's brought out a lot of debate on saw tuning, which can only be good:thumbup: Have a good Sunday afternoon everybody

I will split the last two comments a bit no offence meant - if caused. How can you tell 14k rpm if you don't have a referance? After seeing many photos on here of siezed saws and reading Spuds posts on tuning, I stopped guessing and brought a 'tiny tach'. My day job is medical engineering, so it's all relying on calibrated instruments, but I see a place for 'working by ear' as an approx check only (I used to set up 132kv switches and could guess the operations times to within a few 1,000ths of a second) - problem is it's so far out when tested against a tacho. Example one, I fitted a twin port to my MS460, so I knew it would be too lean, I warmed it up and set it to 13.5k with slight 4 stroking, which evened out under load - so that worked. Example two my MS280 (10yr) sounded much the same with the H screw in or out, so it could be at risk. I removed the restrictor and set it to a max of 13.5k - yet to try it on some wood. Example three my lads new MS200T, now running a bit high at nearly 15k, it sounds a bit fast but most of the MS200T I've heard do scream a bit. Now set to 14k does sound a bit slow for what I'm used to along with his MS260 at 14k. Hopefully later I will test out the 'tiny tach' against my sons XT660 but that's at say 7K. If not I may set up something using an oscilloscope to check it out.

I found my MS200T was picking up speed after say x10 tank fulls, so set it back, I had to remove all the H restrictors (using an 3.5mm tap) to get the speed down on the saws. Bit odd as I have heard loadsa MS200T running fast and I assume they were ok. Need to find a way of checking the calibration of my 'tiny tach' May try and used my son's XT660R - when he's not around

Checked out most of my Stihl saws and they are all running 1k rpm to high, so had to removed the H restrictor to get the revs down. Will give them a good work-out soon on a few boughs and see how they run. may put new restrictors on but at a higher setting.

Yrs ago a landowner walked up to a large group of 'alternative caravners' who arrived on his estate, and told them, 'to move - or you are mine' they laughed at him, not understanding what he meant by 'you are mine'. They found out he ordered his men to build a gaint bale inclosure around the caravans. Bit of legal action kicked off but he got away with it by claiming he always built a large bale stack there. The only way they could feed themselves was for their kids to climb the bales to catch food been thrown over by there friends, in the end they pleaded with him to let them out.

I though it read 'The real RA' - things havent got that bad. have they:confused1:. I like walking but alot of paths are still obstructed now by 'new country house owners' who buy a house knowing it's got a path running through the grounds and then apply to have it closed or diverted. Plus local farmers who put very lively cattle in footpath field but not other fields to put people off using them - oh yes they do:thumbup1:

check if you are also buying the shooting rights - know a few who have been caught out by that one.

[To this day I can't understand why I didn't get out of the way! I have had that happen a few times - once standing by a cliff looking up when a fist sized stone came down, I froze but had to pump my legs to move, the other time at a traction engine show standing infront taking pictures and it moved (driver couldn't see me) again I froze but had to force my legs to move. Sounds daft to be run over by a traction engine at 1mph With tree felling I can relax and move when needed no prob, or I wouldn't be here. I spend alot of time on a large estate working and walking and have had nearby boughs just drop, no warning - no wind. Heard one story of a tractor driver on an estate who stopped to chat, then as he moved off a large bough dropped in front of him - lucky. When it's really windy on this estate - odd how my phone does'nt work till the wind dies down.

Was it new stock? I picked up an Elwell 6 with the lable still one - never used, from a boot sale. I knew a retired old boy who used to go to farm sales to buy up old tools, I then used to look over them and buy the good ones. Built up quite a collection, must get back into using them.

Had this problem with a ms260 when new 7 yrs ago - never found out the cause, just had to keep checking it. Sometimes if everything is ok wear wise or crud in the sprokets, it could be simply the expansion difference between the bar and chain - check it cold before starting, again when hot and when cooled down in case it contracts and puts too much tension on the crank bearings. Plus I have found all chains (bikes included )will stretch unevenly, cheaper ones are worse so spin and check when adjusting tension.

Yep according to my wife who's a nurse it's fairly common - go and see your GP

Wow - that's so envio friendly I would put in a glass case and get my frigging old axe out again:thumbup1:

Still I'ld fit a 'flame trap' to save burning my butt if I swallowed some:blushing: Back to fuel fumes, my wife is a Practice Nurse she tries to stop people smoking (90% waste of time) but she has this CO (carbon monixide) meter, I tried it after a saw session and it gave a reading for a regular smoker - not good for your health. For info, CO fumes when inhaled are taken up by red blood cells instead of 02 so it's possible for high levels of CO fumes to in effect - drown you:001_huh:. The CO when absorbed stays in your red blood cells untill they are replaced. or in effect you are on reduced 02 so never at your full lung efficiency.

I can see it coming up the side of a hedge, flywheel spinning I used an even smaller MS170 for that job - keep it sharp and clean the muffler and it's brill for hedgelaying with it's narrow nose bar for pleacher cuts and cutting stakes (or is that cheating) Or use a Yorkshire bilhook one handed

Many thanks Gardenkit. I used to do alot of backpacking and found the Coleman stoves using their own fuel (white gas) gave out less fumes than unleaded. It's good to enjoy the clean mountain air without feeling like you are in a traffic jam - guess it's the same with your fuel in the woods.

How much difference in say Carbon Monoxide or Dioxide does it reduce emissions? I'm interested as CO fumes make me feel sick so I use saws with a respirator mask (got nicknamed the 'masked chainsaw man') And the amount of fuel I use is low. I was reflecting on technology developement in the last 35 yrs, my day job is a medical engineer, when I started patient ventilators were driven my 3-speed bike gearboxes with chain drive, this went into 80's tech and now to service a ventilator it's no more boxes of o-rings but plug a laptop in. Say x5 totally different generations of models but with say a chainsaw, in a way it's the same model concept with alot of upgrades, because a 2T motor works.

yep but 'Fritz' had the ME262 you can fell any tree with x4 20mm cannons - You will wear black PPE and dye your hair blond:thumbup1: Back to the topic, as an engineer - I can't see how for: price - weigh - power that the present generation of chainsaws can be replaced or converted to a new technology. The % of greenhouse gas produced by man using chainsaws against all other energy use must he less then 0.00001% but we need wood, so why not make pro-chainsaws an exception - simple:thumbup1: The total chainsaw 'greenhouse gas' output would be less than 'wasted energy'. The idea of some kind of 'new green technology' can save the planet is not real or practical but to some going green is a new religion but you still need wood

How about a direct drive steam turbine that would reduce the weight a bit - pity about the backpack boiler:thumbup1: Thinking about your Nuke -saw, maybe that's why the Iranians are going Nuke:confused1: Lack of oil and a big tree problem:lol:

Interesting, it would suggest new saws are setup when still tight so will over rev when run in by 1 - 2k.

You would need to fit a urine catheter to the operator then, or an 8-generation relay team, that would glow in the dark. Don't even think about putting one in a submarine:001_tt2: Steam chainsaw - now there's an idea, superheated

Maybe 'landrover' are making one - will leak oil, weight a ton:sneaky2: Hang on a few yrs and we could have a reliable Jap one:thumbup1:

Firstly glad to hear you are ok, and thanks for posting as it should help others to avoid the same happening to them. I used to work with mobile cranes both UK Brazil etc, some drivers gave me the creeps, should have refused to work with them but saying that all the overseas drivers were good, no common lingo but felt safe working with them. I have had incidents when I have felt life is fragile, worry about my son going into the business.
