NW Surrey near M25 j11

Prunus of some sort, probably flowering cherry. Grub the stumps out whole when you dig the extension footings.

Part arrived as per L&S usual prompt service, and fitted, much better but air still getting into bulb and hi running erratic, it's definitely fuel starvation as saw runs fine with finger over the stratification throttle body. It makes me think the fuel hose was were degraded and broke when I took the carb off. Normally at this stage I would swap carburettors but don't know of another ms181c I can borrow off.

That's an Einhell saw, not something I've taken apart though I was given one and it works. I found a diagram which may help to separate the handle/tanks away from the engine

Yes I thought the fungus largely re infects the current years growth from spores produces from the previous year's growth.

I don't know but I also replaced the pipes to the bulb as they were a bit stiff.

Well I own neither a 545 or 550mk2 but we had both on garden arb jobs when I was helping out last year and for general branch snedding for the chipper I would pick up the nearest and not notice much difference, logging up and the 550 was worth walking to get.

Funny thing is I have never come across this problem before. I could have fitted a plain plastic fuel pipe instead of waiting for the new piece to arrive but as I only keep standard stihl small tube and had nothing bigger bore to hand I lashed out £6.75 on the moulded piece. It was one of three stihls I was given to fix last Monday and now I suspect the bulb was only ruptured because it was pumped so often to get the thing to run at all. The others were to replace a snapped throttle trigger, easy, and a spark plug blown out of its hole, to which I fitted a helicoil.

Not fixed as I expect the piece in the post from L&S tomorrow as I ordered it just before middday. I couldn't see it was damaged when it was in its little clip and strangely it wasn't leaking much petrol, just sucking it in when the bulb was pressed. Fingers crossed tomorrow.

Yes

You'll need to check the voltage of the motor, also there should be some numbers on the little Peltier device, the little square thing clamped between two plates. If not see how the fan spins with just a single AAA cell on the two wires attached to the motor. Have you a link? I think you are being very over optimistic. Come over to the off grid thread and discuss. TEGs produce up to 4% electricity of all the heat that passes through them from one side to the other. That's with the hot side at 300C (if the solder will stand it else only 300C) and the cool side at about 25C. as the cool side warms up the output goes down. So you would need to poke about 2000W through a module to get 100W electricity out but all the heat would have to be removed at 25C so not hot enough for DHW if you maximise electricity out.

Thanks, I had replaced all those. It turns out it was a split fuel hose from the top of the tank to the carb.

I only know of some about 100 miles away.

The prinmer bulb is sucking fuel from the carb and dumping it to tank. Because it is sucking air from somewhere other than the tank this air goes to the tank and pressurises it. This is why I asked the original question; can the air be being sucked back from the jet and into the metering chamber? I have replaced the gaskets so will give it a try tomorrow as the gasket to the metering chamber was split.

By stuffing more air into the engine and injecting in the fuel much faster and finer. I wonder about this, is a modern 2 litre transit engine lighter than the old duratorq 2.4? The thing is the cubic capacity of the engine doesn't matter once you have a supercharger (turbo) an engine depends on the mass of air it consumes and how near to stoichiometric fuelling you can get to plus how near to burning it all before the power stroke has started. After that the components like block, head and cranks etc. have to withstand the forces and this will lead to them being equally massive. Yes increased pressure but probably lower compression ratio as you are now forcing more mass of air into a smaller swept volume. When I last had to deal with a cooked transit 2.4 engine it was far cheaper to buy a new engine at £2000ish than attempt to rebuild the old, the gasket set alone was £500 but that was several years ago and only one out of a fleet of 6. They tended to start having injector pump problems at 130k miles but that only cost a few hundred.

Yes it is hard to decide from photos but the planting spacing and height of clear stem demonstrates the difference between British and French sylviculture. In england I think all the hornbeam woods I worked were out of rotation coppice. The french way seems to go for long clear stems whereas we tended to aim for short fat butts of oak with large canopies standing out as islands in a sea of underwood. I would thin it very gently as the crowns seem very thin and ideally should never get to be less than 40% of the height so it will take time for them to exploit any new space you give them. What is hornbeam used for in france?

Yes they were both great. They both looked up to me as the big brother but I bullied them relentlessly :-(. They were both very successful whereas I just managed to struggle through and they both helped me out on numerous occasions. Just me and the youngest left now out of four baby boomers.

Me on my first ride of the CBR250R in late 2017, the day my younger brother gave it to me, he'd only bought it a month before and never rode it. As I have a poor circulation in my arms the weight on my wrists gets bad after a few minutes unless I can keep above 50 and let wind pressure relieve the weight. It's relegated to be my shopping bike. I preferred the Kawasaki GPZ 305 he had given me a couple of months before. Better power to weight and riding position but the old tyres ruined the handling. The engine packed up on that so I reluctantly scrapped it and my youngest brother funded the MT07 which I use for longer trips.

That's right As I said I broke the HI screw limit cap to open it a bit more but no difference. This Zama carb seems to have a fixed main jet and the HI screw then provides a bit additional fuel through an adjacent hole from the diaphragm chamber. Yes all done and I shall fit a fresh fuel tank filter, even though the current one seems fine. I'm just wondering where the air is getting into the purge bulb from. Repeated pumping definitely pressurises the tank. I will have to check bulb housing for a leak too but why should an air leak here weaken the HI fueling?

How much is a bit, I thought normal was level with the base?

That's the only big one if you are confident about the others and they are common with just living in any case. 50 miles and back is a big bike journey for me and my first ride this year was only 10.

I have no ability to judge when a social interaction is going wrong

I skimmed through that but it mostly seemed to be a sales pitch for fuel cells, agg221 gave reasons why these are both delicate and a bit far from mainstream still. If I were to be forced off grid I'd plump for a mains changeover switch and running an LPG converted Honda EU200i for a few hours a day IF I could figure how to prevent the demand from the house overloading it when the 6kWh battery pack couldn't take up the slack. Shame there doesn't seem to be a water cooled option. The idea being that as my system depends on the grid for the PV to charge the battery I have to have a good sine wave present mimicking a grid presence at the consumer unit to keep it all working.

I can't say on @Baldbloke's dilemma, Gunga Din. I have hardly travelled outside UK at all but did hitchhike off the airbase in Finthen to home at 17. You can buy years back in but when I unexpectedly retired at 65 on full £150/week pension my slightly older friend hadn't paid in for 15 years but was still entitled to a £90/week pension. I've overspent the state pension by about £8k/annum for 5 years, mostly due to family problems, but picked up much of that from little jobs. I'm going to take some private pension from here on. So if the mansion in Scotland can pay for itself and you can live the dream for 2 years... I wouldn't dare but then I have social problems

A question for the experts; I have a ms181 on my bench, it had a split purge bulb which I replaced expecting that to cure any trouble but now the saw starts and ticks over but fluffs out when the throttle is opened. It successfully revs up if I put a finger over the stratification throttle body.All the signs of a low HI jet setting . I broke the limit cap trying to open the HI screw but this made no difference. I have opened the carb up and checked orifices and strainer and am about to put in a new, highly expensive, Zama gasket and diaphragm set. The one thing I did notice was that the purge bulb drew in some air and I am wondering if a restriction in the fuel supply could cause the purge bulb to suck air back out through the jets??
