new piston rings perhaps

Interesting, if when it's running you see no smoke then you're getting all the heat of combustion out of the log, smoke is unburned fuel. So as long as the flue temperature is around 150C and no air leaks then I'd guess no benefit. Air leaks and excess air are the biggest wasters of wood heat because of the extra mass flow up the chimney. However the Jotul 602 I replaced with a morso 11 was less efficient, wasted heat up the chimney and smoked a fair amount of the time, especially after reloading. The modern fires with firebrick insulating combustion chambers burn hotter faster, so unless I cock up my fire is smoke free withing about 15 minutes of top lighting.

Yes worth noting for the unwary, especially if not VAT registered, that adds 45% to the bidded price
-
Yes and I wonder how much that is due to a general reduction in rabbit population, whereas roe and muntjac seem to have increased but less damaging?
-
Lovely butts @lewiswood and very tidy work. I could never afford to buy parcels as good as that.

If you go down the ceramic route never sharpen it with a stone or diamond, the effect is the opposite. Polish only. I prefer steel but do use sabatier stainless knives for carving and dicing veg, even though carbon steel can be sharpened more keenly.

Pressure relief valves absorb most shocks, port relief valves on individual spools if the shocks are from external loads.

No question in my mind there is no other way that's not discriminatory.

Yeah I went back and looked again on iplayer and saw it was already broken. I certainly wasn't disparaging the skills of the workers. I am aware of the filmmaker's desire for hype and drama. Okay, we would often have to skid big butts out but would stick longer (up to 40ft) bits on a trailer with the wheels set right back, to avoid mud getting on the timber. This did reduce the weight, and hence traction, on the county wheels so front weight had to be added in the form of a big log extended in front of the blade. Where possible timber quality oak would be felled about now till March and brought out when the ground was better in May. Shame, ask for the footage. I am aware of how much ends edited out as I was involved in a day's filming a long time ago, I think only about 15 seconds ended up in the film but at least my 10 axe blows and the tree coming down was kept in. How are the sawmills feeling about strength of diseased ash once milled?

Alternator ppr...? Anyone heard of it or know anything about it?
openspaceman replied to swinny's topic in Large equipment
So the alternator runs about 1.5 times engine speed? -
L&S supplied me with an aftermarket carb for my Stihl long reach hedge cutter at just over the cost of a carb kit, it has been faultless so I wouldn't discount them. In this case it is not necessary as I put the carb back on the saw, set the screws to factory 1 turn Lo and 3/4 turn Hi, primed it with the purge bulb with hardly any bubbles of air and it fired first pull. Started on tickover and after quite a few seconds of fluffing revved up and cut well. Idle is 3500 and Hi idle 12500 rpm. I don't know what caused it to change but it may have been the carb cleaner. I only replaced the tank filter, fuel line from tank to carb and two lines from purge bulb And I forgot the pump and metering diaphragms and gaskets.

Is this just a TFL thing? Is that just in a zone or return journey? Not that I have much intention of visiting the smoke I think my little used bus pass only works on buses.
-
Please explain that for a pubtransphobe
-
I masked off the two holes, applied carb cleaner to the H screw hole and it all squirted out of the jet in the choke tube. I shall put it all back together and clean out the fuel lines and see what happens. I checked out those cheap carbs on ebay but the nearest match to the C1Q-S192 seems to be ZAMA C1Q-S269 which fits the ms181, is it likely to be much different from what I need?
-
Stick a smaller inline fuse in then, remember the fuse doesn't protect the stress control it protects the cable and gubbins upstream if something shorts in or near it.

Interesting and the chaps felling the ash knew where they were at; felling it flat on the fork to stop it splitting down the butt. It would have hammered over but they made the mistake of adding the tractor pulling for entertainment and they miscalculated the rope length, it cost them a back window by the looks . I wonder if they reported a tree falling on tractor under RIDDOR. It seemed strange they would skid logs out on that flat ground, even stranger to see a mill yard that muddy nowadays. We only supplied beech to Smiths for Ercol but did attempt some woodmizered ash squares for another company that imported from the states

If you fancy a bit of restoration I have a very tatty 1164, not a nasty flat floor model.
-
Yes a complete anachronism but very british
-
Thanks, I will also go and read the whole thread . This carb has a white plastic plug there. Thanks I'll try Spuds idea and I'm not bailing just sitting back for a bit. I have some fairleads to fit on the County and see if I can get the exhaust manifold off. The earlier thread mentions an after market carb which I will investigate.
-
Yes I think so and posted such earlier. I think so but the main test will be to try Spuds suggestion and block both ports from the metering chamber and see how much comes out of the choke. Nope, cannot see it has one
-
Well thanks again for top input from you both. Idle was on near enough factory setting. I've not done more with it today and as I said I don't intend taking the carb apart any further as repair is uneconomic if the carb is the faulty bit.
-
@bmp01 That's all very helpful but I take it that last picture is a check valve and main jet and it probably sealed beneath the welch plug. See picture: The red ring is what I take to be the main jet hole and the its brass jet. The green ring is the bypass to the main jet controlled by the H screw directly above it with the damaged limit cap. The yellow under the needle valve lever is the idle jet and welch plug. I don't know what the purple brass plug is and the blue is the welch plug under which I suspect is the check valve. Green and red are connected as carb cleaner bubbles out of both when squirted through the H screw hole.
-
Thanks for the explanation, I thought it affected idle jet. I have checked the screen between the pump diaphragm and the inlet needle valve and that is clear. With the main jet out and the Hi needle screwed in to stop air from getting past its hole in the metering chamber and a fuel tube pressed against the main jet hole there is no discernable difference whether sucking or blowing though I think it is no more restrictive than the needle jet when the fork paddle is fully depressed. I think if I take out the welch plug to get at the check valve the repair will have become too uneconomic.

Sharpening, Oregon 410 - Getting to Proper Guide Depth?
openspaceman replied to FlyFishn's topic in Chainsaws
Yes but I felt you had to push harder on boring cut with a chain that was nearly finished -
Not tried putting it into wood with strao blocked, maybe when it goes back together. I've done the carb cleaner down the main jet and taken the brass main jet out and it is clean. I thought the check valve was only on the low screw circuit. I'll re check the strainer this afternoon. @bmp01 it's a 2011 saw.
