I'm not sure about previous years, but this year the very cold wind we had in spring just as the the buds were opening (was it storm Hannah maybe?) hit the sycamores (and beech) really bad, lots of them haven't really recovered and have a thinner canopy with smaller, brown edged leaves.

I'm slightly confused at how 1kg of wood can produce 1.65kg of carbon dioxide, didn't realise burning things created mass!

what sort of Yorkshire man are you?  Impostor says I - bet you drink tetleys and put the heating on instead of a jumper as a true Yorkshire lad would have packed the wound with sawdust an gravel, topped off with a bit of moss and held in place with a grubby handkerchief  if need be- and if it got a bit funky, rinsed out with a bit of spit and best bitter when suppin after the days job - waste good money on plasters? - no yorkshire man i know ever would! 

I have a slightly mystifying problem - my 445 will start but not run. To elaborate, no matter what starting method I try, be it choke on, high idle, no choke, holding throttle etc, the saw will audibly fire after a couple of pulls like normal then die instantly. I can see exhaust coming out of the muffler and the plug definitely gives a spark, I don't think it would be fuel line or carb related as the saw still fires perfectly normally, but only when I'm pulling the cord!

The issue began on friday when I picked it up (after it having worked fine just minutes before) and it just refused to run!

Anybody got any ideas before I start needlessly replacing random parts?

Yeah
 
I'm not convinced of the utility of these bulbs and as this one is remote I shall stick a haemostat on the pipe between the carb and bulb, it should perform just like an old fashioned saw. If that's the case then the only advantage in the bulb would be in cooling the carb??

Mine was seized solid when I got it I had to beat the piston with a rod after I poured penetrating oil down the plug hole and stood it overnight. I was doubtful about the cylinder when I cleaned it up and just put a cheap eBay piston in it but it has been perfect since. It has no decompression and is a 12mm pin model with manual choke, runs well.

Anyone breathing in plastic today?  Well apparently we all are.  I am referring to the revelation in the recent BBC TV programs that even inside our homes the air is full of tiny plastic particles.  Not seen the programs?  They were called "War on Plastic" and were very well presented by Hugh Fernley-Wasisname and Anita Rani.  They did talk about the plastic in our oceans as highlighted by the Blue Planet documentaries last year, but they showed that pollution in the seas is only part of the story.
 
Please watch if you care about our planet.  I thought I was well informed of the plastic problem, but I was still taken aback by some of the images of what happens to our so-called recycling and waste.
 
If you watch the program and are still happy buying plastic products you are very different to me.  And never again will I allow my children to have a Macdonalds Happy Meal toy.

Just awoke from my siesta,
(It's my Bday)
To find these from the neighbour.

Strange job to give a new bar and chain. That’s the last job they should have, not the first. 
I guess you know that now of course. 

We got hit really bad in Pembrokeshire, exposed hedges and trees all dead and brown down one side - rather unsettling driving around and seeing trees in autumn colours in may!

Haha, I was looking at some pictures on internet over weekend of exactly the same type of thing. Just need to find a good supply of horse shoes.

I'm in Northwest Pembrokeshire, and here's what I've seen out so far this year -
Hawthorn, hazel and elder coming into leaf from about a month ago
Some buds on beech getting fat and starting to burst about 3 weeks ago
Sycamore buds bursting from about 2 weeks ago
Blackthorn flowering from about 1 week ago
There also been a few other fruit trees flowering for a while now :-)

Rob d of chainsawbars.com has a thread at the moment with offers on 13" sugihara bars and husky chains, though 13" may be a bit short :-)

I assume they'd fit a 445 as well? :-)

The mix is 50:1 petrol to two stroke oil, i.e. for a standard 5l plastic petrol can full, you'd want to add 100ml of two stroke oil. :-)

I'm really glad this thread came up as my 560 has had a mysterious chain oil leak ever since I bought it! Anybody have a picture showing where the bolts are? Still learning all the names and locations of the myriad bits of chainsaws!

I thought the main advantage of this Winch was the fact it’s Hydraulic Driven, with the Motor acting directly onto the chain.
It means you can mount it easily on the front and rear of a Tractor with no need for the PTO.
 
Handling chain is easy, you can choke it back on itself or hook a shortening clutch on at any point.
 
I don’t know how you go on with Snatch Blocks for redirecting, but I’d assume no issues?
 
My only concern when I looked at these was access to clean the inevitable shite the chain will carry back with it when conditions are bad.
 
 
Eddie.

Great to see you have it sorted. Spud explained far better than I could. [emoji106]1: I have only repaired two and I didn't bother with any epoxy resin, both are still working fine to this day.
 
 

I remember somebody posting a link to a silky scabbard made by someone other than silky but can't find it with the search - anybody have any ideas? The hard plastic official silky one likes breaking too much :-P

For a silky sugoi 360, any ideas appreciated!

I have heard a lot of people complain about how the anti-kickback raised drive links on chains slow the cutting speed through the wood.
Can the type of chain you use affect which trouser classification is most suitable?
I presume the chain speed of a saw is calculated not under load and travelling as fast as the saw will allow it to.

Yay, all fixed! Bit of a bastard to align the hole correctly when drilling from the outside, ended up drilling 2 as first wasn't quite on target - might put a bead of epoxy in that one but leave the correct one free in case I ever have to replace that stupid little pin again!
I even managed to get the spring back in and fully compressed using only the workmate and a pair of snub nose pliers, second time I've had to do the spring and it's still a PITA! But at least I can use my saw tomorrow ^.^
Thanks again everybody!

Thanks very much Spud, a very clear and comprehensive answer! I'll probably give it a go today - as much as my little 445 punches above it's weight, I miss the power of my 560! :-P
I was thinking that even if I eff it up then a new clutch cover ain't a huge cost, but it's far better to have been armed with knowledge first to make that scenario less likely. Will post the results of my attempt later! :-)

Thanks for replies guys! I was thinking about drilling it and putting a screw in but figured the exact same thing; it seems like the metal the pin is made of is very hard and I would just end up damaging the inside of the clutch cover around it, especially as I have access to neither a vice or pillar drill - I'd just be asking for trouble with a workmate and battery drill!
I also don't have access to a welder and would rather not pay to have such a tiny part replaced :-P
Mark and/or Spud, just to check - you're sure that drilling a hole from the outside of the clutch cover behind where the pin is in order to tap it out will have little to no effect on the overall strength of the clutch cover?
Cheers again!

Hi guys, the little pin that acts as a hinge for part of the chain brake system in the clutch cover has sheared, and now I can't get the bloody thing out to replace it! I have attached photos of the broken pin in the clutch cover and the replacement part.

The ridged section of the replacement is the bit that goes into the clutch cover, and the extra friction from those ridges and fact that I can't really get any purchase on the top as it's sheared off flat had made it a right PITA!

Anybody experienced and solved this problem or have any advice?

Cheers!

Your accusation has shocked me !!!
