I had the opposite on a 2stroke. Idled but stalled when you tried to rev...

First thing I did was pul the carb... Took it apart, cleaned it all nice, checked gaskets were seated nicely, cleaned needle etc etc... problem remained.

So I looked at everything else, cleaned the fuel tank, and replaced with nice E5 petrol mixed properly. Took the fuel filters, air filters and exhaust off and ran it like that and problem remained...

At this point it was pretty much stripped down to a fuel tank, carburettor and cylinder head, and of those 3 the thing most likely to go wrong is the carb.... Got a new one and it's run perfect ever since - musta got clogged somewhere I couldn't get to with cleaning

So might be the carb giving grief even if you have cleaned?

I bought a brand new ((old stock) briggs and stratton engine cheap
It ran perfect, I parked it for the winter and come spring it would rev but wouldn't tick over
Tried everything, eventually bough cheap carb off internet and it's run perfect ever since

Which is why I posted up thread :
"So the two stroke has a spark.
so I ordered a noo carb."

Only trouble is, if you want it quickly you have to pay silly money like €70 for one.

I read an interesting fing ont tinternet saying that even if you run the carb "dry" there are still droplets of fule that sit in it and can then turn to the dreaded lacquerlike gunge. The bloke said you could use carb cleaner and blowing it through but then you would need to wash it in soapy water, rinse it and then blow it dry as the carb cleaner tends to just lift it a bit and move it slightly. In other words carb cleaner doesn't even do it all that much good, but impying that there was little else you could do other than buying some stuff called "Mechanic in a Bottle". So it may well just be an advert.

Others say put it in an ultrasonic cleaner.

But a lot of us seem to be having the same problem. I now have two with similar problems all down to the carbs.

I managed to buy some proper carb cleaner today, but I think the diaphragms in both may well be past their best as there are slight wrinkles in them, although they are whole.

and this is after using 98 octnae petrol rather than bog standard cheapo stuff. The instructions clearly state "lead free" other wise I might have gone for Premium or the equivalent of "leaded" stuff.

Old fuel can sit in a carb over winter and turn to varnish like gunge, if it doesn't block a gallery it may restrict it enough to be a pain, carb cleaner needs to be soaked for a while I reckon and then followed with a blast of air ...

I just fired up my 12.5 hp Kohlar engine after more than 3 years
There was a little old fuel in the float bowl which I tipped away.
The motor fired almost straight away and ran beautifully
So the fuel didn't turn to varnish and it didn't harm the carb
I can't think of a reason why

There is a I believe a school of thought that says fill the tank to the brim and leave it like that.
All I know is that ever since I bought most of this machinery in about 2010 it has worked well on start up after following the "empty it out and run the carb dry" advice, and the chainsaw still does, as does the big 3 wheeled brushcutter, which is 4 stroke.
I am beginning to wonder if the particular design of brushcutter carbs is a bit to blame.
Or has the petrol simply got worse over the intervening years? I know the ethanol content has got higher.

The article I quoted pooh-poohed the stuff you can put in to stabilise the fuel, as well.

Then I read, or got part way through, an extremely long thread on a Merkin forum about whether to use "Stabil" or another stabiliZer. As usual everyone had done the same thing for 20 years and it always worked for them, and they'd all done different things. :rolleyes:

seeing as I have done the diligence and discovered that noo carbs for Ryobi are either quick to get hold of but expensive, or cheap but take ages to arrive, I think I'll try and get hold of a rebuild kit for the 4 stroke and in the meantime follw @Brown 's advice re soaking in acetone, as I can get that easily over here. The only compressor I have is one that plugs into the aux socket and blows tyres up, but it is pretty good. I have a convertor I can use to plug it into the mains so I'll try to use that to blow things through.

all good fun, sometimes!;););)

.. the the blood test came back and they can't measure my lipids properly because my Triglycerides are too high (it messes up the analysis). But the total Lipids are 8.5 and the TG are 4.7 so the other two jokers are 3.8 between them (ratio unknown).
So the high TG I can understand it's probably entirely dietary and borderline Alkie drinking levels.
When I said I did not want statins he offered summat else, but on looking that up it says "interaction with other meds is unknown" so I will pass. I need to have a word with myself about the alcohol (clearly) and sort something out. :)

I liked your post but really I am expressing fellow feeling and worry as high "stuff" in your blood cannot be fun.
I too have been recommended statins, and maybe I am sticking my head in the sand but I also told the doc "No".
Whatever you do, look after yourself.

I am of the opinion that the human body has evolved over millennia and doctors have evolved over centuries.
The human body is equipped to run on several sources of energy. Carbs, proteins & fats.
Carbs = Diabetes and the old diatribe of have a heavy carb breakfast is being disproved all over the place.
Even the NHS has recanted that and is putting people on low-carb high protein diets to fix type 2 diabetes now.
I know I am alcoholically "over-medicated" (to my eternal shame) and I am trying to resolve it.
I was taken aback by the Drs admission that the "good LDL/bad LDL" was made up by the medical profession to make it simple for the masses to understand and therefore to get them to accept statins, but knowledgeable people would understand that it is the ratios of good/bad that were really important. This really told me all I need to know. :D

I've known the Goodldl/Bad ldl thing a long time now, and whenever i ask for the two figures they can't or won't give them to me!

I think that they are rather obliged to give full disclosure.

My understanding is (from a PUBMED paper) is that the preferred/ideal ratios of lipids are:
1715287052388.png

So you only need a few figures/checkpoints to work out for yourself if your lipids are Optimal/Moderate/Or High.
When I challenged the Dr. on the phone he "folded". Maybe because he realised I was not a pleb.

I've had some success with two stroke carburettors by immersing them overnight in a strong solvent like acetone or thinners. If they're a diaphragm type I take the diaphragm out, in case the solvent damages it. This helps dissolve the congealed two stroke oil in the tiny holes.

I was told once by a mechanic in a shop that sold strimmers and chainsaws to reduce the amount of oil in the petrol. I'm reluctant to go too low, however, because that's the only source of lubrication. This man's business relied on people buying new ones, so I don't suppose he minded them wearing out quickly. I'd rather risk a drop more oil and keep the engine intact for longer.

Reduce the oil in a 2 stroke :oops: was he having a stroke ffs 🤣🤣 My strimmer think its a jcb 20 years old & I use it once
a year. It goes through 2 tanks of fuel also I have a cheapo b&Q chainsaw pro somit same 20 years old.
Both never had a new plug or fuel filter cause id just chuck em than spend any money on them, anyhoo when they run out
of fuel I fill them up & add 1 cap full of 2 stroke oil into the tank & give it a good shake to mix 🤣
They always start n run perfect in fact the little saw out ran my mates Stihl & Huskey saws when they were running all morning
then wouldnt start n cutting out the little saw never missed a beat. 🤣🤣 His face was a picture. :D:D

Been warm and dry today.
Went for a "big shop" and the shops we needed were all open, at least in the morning.
Had lunch outside :eek::eek::eek: for the first time this year at our usual brasserie. I had "moules roquefort" which I have never tried before. I recommend it!!
Have a good evening folks!
