Damn. Not such good value. £42Thanks chaps. Hadn't realised the replacement carbs were such good value. I'll give the mixture test that was suggested first but failing that will get a new one.

Checked and all OK.Starting and running at full chat put very different loads on the engine and it takes 2 minutes to check a spark plug gap. I can only tell you that mine started easily but bogged down when I opened the throttle and the issue was with the plug. Doesn’t mean you have the same issue but it’s such a quick thing to check before a carb strip down
Watch straps, jewellery anything with fine structure that won't harm in water.Checked and all OK.
Small cleaner ordered from Allendale. I counted up the number of two-stroke engines I have...5 So I reckon the ultrasonic cleaner will be a good investment. Wonder what else I can use it for ?
Due care please.If you just put the item in a jar and sit that in the water then you can use pretty much any cleaning fluid in the jar, Alcohol or lighter/Coleman fuel being good ones. Lighter fuel is particularly good at removing oil and grease.
Personally I wouldn't waste your money on specialist ultrasonic cleaner fluids, you will get just as good a result in water by just adding a few drops of washing up liquid.
Usually helps if you leave the item to soak in your chosen fluid for a while first.
My local jeweller, a proper one who actually makes stuff, did a repair for me on a watch case. He cleaned it afterwards and I was very impressed. When I asked him what fluid he used "warm water and fairy liquid".
Fair point, although I doubt most small DIY machines can can hot enough for that to be a concern. I generally run mine at about 35°c.Due care please.
Find out the ignition temperature of whatever liquid you use, with respect to the temp you set the bath.
The part that causes the issues is in top part of carb when open up it's a tiny Gauze filter remove with something like a bent safety pin! or squirt in place but making sure engine isn't running too long on carb/brake cleaner type stuff as "No Oil" Easy to diagnose! if fires up ok on choke but won't run off properly/cuts out/won't respond to throttle.Success. Started first pull. Reve'd up without any hesitation and so thanks to one and all.
In the end I opted for Allendale's carb cleaner since I reasoned that they wouldn't sell anything that didn't work as they have a good reputation to keep. Not bad value as it's a concentrate. Currently got a pair of specs in there and ewatching the verdigris fall off !
It is amazing sometimes how much dirt can come out of something that looks relatively clean. The old style expanding metal watch bracelets are a good example. In a big jar and ideally over a bit of tube or mounted on a bit of thick wire so as to open them up a little. Often have to repeat the process multiple times as the fluid turns to something like soup the first few times with all the accumulated muck coming out!Success. Started first pull. Reve'd up without any hesitation and so thanks to one and all.
