There was a lawnmower discussion here

Yes it was off-topic., so I moved it here
It starts with reply #50

My Honda mower had a strange problem

  • it has compression
  • it has spark
  • it has fuel in the float bowl of the carby
    but it will not start

I thought, it has to be a carby problem, so

  1. 2 attempts to remove and thoroughly clean carby
    will not start
  2. buy a new carby… they are cheap $23
    fit the new carby
    will not start

What? There is nothing left to fix

Then , a last desperate try before a trip to the tip… remove
the muffler
It starts right away
The muffler was blocked.

So it was not sucking fuel from the carby into the cylinder , because it could not pump air with a blocked exhaust.
You live and learn.

It does not run very well on the new carby… races… needs governor adjusting I think. I think I will put the original
carby back, that would be easier than fiddling adjustments.

Is this a two stroke engine? I had the same issue with a Stihl weed eater, I pulled the muffler and drilled the baffle plate out, it is a little loud but it runs. Your old carby should work fine.

No, Hondas are 4 stroke.

I think that cheap carby must have its jet sizes wrong … I cant slow it down with the throttle stop, I can slow it if I
hold the governor lever.

I washed the muffler out with diesel and compressed air.
I might drill it like you did, just to be sure.

Mowers are just like computers. Little things matter.

It does, I put it back… idles now.
Complicated carby linkage, I hope I never have to touch it.

Now I can start fixing the brushcutter.

Always something breaking!!!
I got my Miller Blue Star DX185 Welder/Generator back up and running.
Had to replace the gas line and the plug that goes in the gas tank. Could
not find the original but a local parts store had one that works, so far.

That is DC welder with a huge capacity.
What do you use it for?

You can make a fuel line with copper pipe and silver solder.
I did that once in our Nissan.

That is what is great about software. It does
not wear out.

I do a little stick welding, mostly with 6011 or 7018 rods, although the 7018 have to be ran at fairly high amperage. It also serves as my house generator, when the power is out. I also had to replace the 220 volt plug, that got broken, when trying to move the machine with my tractor.

It only gets old and feeble and quits working!!!

Like us.
I use a stick welder, but it is AC and mains powered.
Modern inverter welders are a lot better than the older transformer types. I use 6013 and 7014 mostly.
Those 7018 are low hydrogen… why use that?

We have a generator for power outages… it is only 2Kw but it will keep the fridges going and a few lights. Noisy beast.

Just what I have learned to use, about the only rod that will weld the steel on a tractor bucket. The 6013 is fine for general purpose welding, but the 6011, may not make a pretty weld, is a much easier rod to use.
My generator will run about everything in the house, except for the furnace and the electric water heater.

Your post got me a “earned solved” badge!!! This day is looking up!!!
Am doing an experiment with a Gentoo VM, am trying to install a kernel with the
make oldconfig command!!!

My next project is a new hard install of Gentoo on the new SSD in my large desktop.
The SSD is going to have

  • MX for stability, email, and writing
  • Void for containers and VM
  • Gentoo for R work and programming.

I find it helps if I dedicate one Linux to one task.

What I want to do is write out beforehand every step of the
Gentoo install, and I might even post it here, before I do it.
I have to wait for cooler weather… cant get caught with having to leave computer running for days in a heatwave.
It will be interesting to see if I can get it right on paper before the event.

The 6013 is good for galvanised steel… not as good as a MIG. I have not tried 6011… will get some Ferrocraft 11 and try.

I use hard facing rods too. They do good job on slasher blades. I build up the worn cutting edge with normal rods then coat it with hard facing , then grind the edge.
I did try how hydrogen rods for the buildup… they were OK but harder to use.

You have all the welding experience. I am just an amateur.
There was a guy who worked with me who was a fitter and turner… he taught me the basics.

13

Gentoo is easy now!!! I did a Gentoo install on my little Acer in less than a day.

14

I want a full compile, no binaries for this job.
If it were just some VM for an experiment, yes I would use binaries, but this is a workhorse, I want all the optimising I can get.

Today’s version. Was slashing the front paddock and noticed a very muddy spot.
It was near a cutoff valve on our main water line.
Inspection was difficult… everything under water… but I could feel jet of water coming from base of valve.
Dug a drain, dug up about a metre around the valve, removed it and fitted a replacement ( we keep spares) .
It was not easy getting the new valve in… the line is 32mm heavy duty poly pipe and it is not very flexible.
Just finished before dark, covered in mud , and late for tea.

So yes, something always breaks.
No idea why a poly valve would develop a split?
Maybe livestock trampled it?
