Is that a fried egg with black-pepper in the bottom of the lower filter ?
Ha! no, it’s a trick of the light, a bit of diesel, and some dust from the cutting disk.

Filter porn as promised… Top is the original filter, a Beta branded one, after approx 150hrs. Bottom is the one I subsequently swapped after about 40hrs (a Baldwin). Some of the dust will be from the Dremel cutting disks. I’ve never opened up a diesel filter before: Is the amount of crud on the top filter really enough to stop an engine, or should I be looking elsewhere as well? Note that this is the only filter on the engine, there has never been any pre-filter.
Sorting out the bits to try to clean up the bottom of the tank.

I think I’ve only ever had the tank cleaned once in 20 years, had a yard do it years ago, and I suspect that wasn’t done very well.
The replacement filter got us to below Middlewich and then things started to feel a bit lumpy again so I changed it again. Will see what they look like inside when I get home, and sort out means of seeing what’s at the bottom of the tank.

There certainly used to be a discount for boats based on the Lancaster Canal. I think it was done away with when the Ribble Link opened.

Second pound down at Red Bull was very low, when we arrived a boat was grounded coming up, the weir was running though so I let some water down for them to come up. Three boats then went down but by then the pound with moored boats in was getting low.
It’s been low-ish most of the way from the summit to Hassall Green today, the “summit minus 1” pound particularly so. Shows what time and water do to piling though, big holes below the normal waterline!

If the tank was not drained of water at least once a year, this is likely to happen. You would probably have to suck or syphon the crud from the bottom of the tank via the filler. Be aware that on an old boat, the rudder tube can leak into the tank. If you are unlucky enough to have a flush male plug in female deck fitting type filler, change any rubber seal regularly and smear with silicon grease. It was recently pointed out in a thread that the actual filler fitting flange may not have a waterproof gasket under it (this is a narrowboat specific type of problem in the main).
I will investigate with the Pela pump when I get back, thanks.

I had these symptoms last year when the filter became blocked shortly after filling a fairly empty tank.
The engine (kubota 1205) would run on tickover and for a short time at 1200 rpm then die.
This filter was at about 80hrs. The new filter also blocked quickly so had the tank cleaned, this revealed about 10 litres of water and rubbish in the bottom of the tank despite having always used treatment additives.
No trouble since.
Sounds quite similar. Not had the tank “done” for a few years. Thanks.
7 hours ago, TNLI said:Have you checked to see if there is a hole in the bottom of the fuel tank if it's subject to bilge water. Any leak will involve a 2 way process where fuel leaks out, but a certain amount of bilge water gets back into the tank.
If the tanks integrity is OK, then check the seals around the filler caps or top plate fittings to see if they are letting in water. Using Biocides is not good news, as it can cause a premature failure of the high pressure fuel pump.
Tank is well above bilge level, any leakage of water in would be canal water, but there’s no indication of diesel leakage out and the tank would be almost empty of fuel before it reached outside water level.

Hmm. When I have had fuel problems with my beta it sort of labours/shudders and stops. Some BMC engines speed up momentarily and stop, some Perkins just go slower and then stop. I would bleed the filter and see if it is actually full. It should run if it is. Let it run for 5 minutes, stop the engine, bleed it again, if there is air in it then it is sucking air from somewhere. If there is no air just make sure the 'stop' control on the pump is working. If everything is as it should be then I would pour out the contents of the filter into a bowl and see what is in it. Is there a fuel on/off tap at the tank? It will almost certainly be some sort of fuel problem but finding it can be a sod.
Thanks. It has run for about 9 hours today on the new filter without problems. There was certainly clean fuel in the old filter, as much as I would expect when changing a filter normally, but whether it was full, full I don’t know. I’ll give it a bleed in the morning and see what happens.
hacking the old filter open may have wait until I am home.

My mum had a BV1505 on her narrow boat and one day she had a mechanic working on it and he stepped on the lift pump. Tiny little crack in one of the pipes. Not the exact same symptoms but basically a little bit of air was able to get in and it caused problems.
The (mechanical) lift pump itself was a tiny little thing with integral inlet and outlet pipes rather than screwed-in unions.
New lift pump ordered, I fitted it and it was fine after that.
Thanks, same little lift pump on that engine I think. No diesel leakage apparent though (although I know that doesn’t necessarily mean it’s not sucking air).

Tank air vent not blocked? Electric pump or mechanical? The infamous multiplug on the loom?
Mine stopped the other day, the fuel tap had vibrated itself closed! After 60 + hours running in the week!
I’ll check the tank vent, thanks. Mechanical lift pump with priming lever - no problem using the primer to fill the new filter. The 1305 is a very simple engine, I suspect it would run (but not start) with the loom unplugged. Fuel cock definitely open

Beta Bv1305, about 4600hrs on the clock. Last filled up full with diesel at Middlewich a week ago with the usual dose of Fuelset, and since then worked up to Bugsworth without incident. Day off yesterday, ran the engine for an hour for hot water, all still OK.
Set off this morning and after about a mile the engine appeared to labour briefly and then stalled as though the prop was fouled. Restarted straight away on the key, quick burst of reverse and away. Same thing, so pulled over for a weed hatch moment. Prop clear, shaft turns freely. Must have shed whatever it was…
Set off again, same thing. Engine starts fine every time but as soon as “anything is asked of it” it labours and stalls. No noticeable smoke. Restarts fine. Pull over for a think…. Check plenty of fuel, air filter is clear, so change the fuel filter (last changed 150 hours ago, recommended interval 600 hours, but usually done every 200 alongside the oil filter). Start up and away we go, no issues on a 9 hour run all the way to Macc.
So, presumably a fuel starvation issue of some sort? The fuel out of the filter was clear and bright, no sign of water, no sign of black bug slime or other detritus. Filter appears clean, although I haven’t hacked it open yet for a good look. I don’t have the wherewithal with me to investigate the bottom of the tank, but I’ve given it a good slug of Marine 16 and am hoping for the best.
What does the team think? Early diesel bug outbreak? Tank crud?

Filler will crack. A nice hardwood strip, you could secure it with tiny countersunk screws and hide the screws with decorative upholstery nails.

Kent Green stop does but at the top of the Red Bull T&M flight there is a sluice that takes from the Macc. A couple of years ago when the idiot C&RT employees ran off too much down the flight one night and we ended up listing in the second pound down, the guy who came out topped up the T&M with this sluice which is in a fenced area next to the top lock. He had to communicate with another guy at Bosley to get the water.
There were two blue-shirted chaps peering through that fence as we came up the top lock. Monday, I think.

Came up Bosley two days ago, very little water at the bottom end of the flight, one pound drained dry overnight. Now at Bugsworth, hoping we can get home again! Levels on the UPF and top end of the Macc seem ok.

Rear of bulkhead fitting through forward cabin bulkhead not
accessible (its behind the tiled stove hearth) - unable to verify
condition of joint
If the bulkhead fitting was drilled out so that the pipe passes through it uncut, then that wouldn’t be a joint? Mind you, you couldn’t tell that without taking it to bits.

Been not there for at least 22 years.

As it's a ten minute entry slot, if you can see the tunnel is empty at ten past, no-one should go in the other end so you might just as well go through early, surely.
20 minute entry window at Saltersford, 10 minutes at Preston Brook.
As far as I recall the timing of Saltersford only started when the IWA National was held at Preston Brook, during which both Barnton and Saltersford were timed and operated as a single unit, and afterwards Saltersford was left on timed entry.
it seemed to work satisfactorily for a couple of centuries before that, although reinstating the steam tug would have been nice…

Given the seemingly constant litany of short stoppages (so many paddles and their rods?), I suspect there are a lot of people on the water this year who won’t be back voluntarily next year.

Midland should provide you with a means to get rid of the old one: https://www.gov.uk/electricalwaste-producer-supplier-responsibilities
ETA: I think I took the old one to the council
tiprecycling centre. They didn’t ask what voltage it was.Further ETA: https://www.midlandchandlers.co.uk/weee-policy

There are some bits of the Macc where HV power lines run across the canal at a very shallow angle, so you are passing under and almost parallel to them for some distance. Trundling along there one particularly hot and dry summer day, wearing a short sleeved shirt and with my bare forearm resting along the brass tiller tube, there was enough induced voltage to cause a tingle.

I feel there is a third issue here: accosting a Licence Holder (or anyone else really) with a windlass.
What if it had made contact with Nick’s head????? A possible charge of GBH or manslaughter, depending upon the outcome?
Accosting? As described what is alleged is assault by beating, and should be reported to the police.
