If the FAX doesn't work, try carrier Pigeon and no eating it...it isn't big or funny

Ah....a Kent Dessert....that was where I had it at school and it was sickly for sure.

The only comment on school dinners I have is "What was that Gypsy Tart stuff? I only had it at school and have never seen it before

No change of thought here as I have had them in bits before so know how they are constructed. All they do is to stop any high speed circuit action at idle so the low speed circuit can do its thing by itself. In regards to the "So crud could be either side of the flap to foul the working?" ....Yes, if the valve is stuck shut, the high circuit is shut down making idle fine but revving out near impossible. If you give a blast of carb cleaner down the H screw hole, you should get a good blast out of the check valve in to the carb bore.
-
My thinking is that with the engine running, there is air flow through the carb so if a venturi in the bore of the carb is open (an open faulty check valve), fuel will be pulled up through it. I know the check valve seals in the other direction but it still requires a reasonable amount of airflow for it to open as it would when the throttle valve opens from idle and enough air flow opens the valve. This is probably like discussing religion and isn't helping the fella fix his carb......like I said.....he is lacking high speed fuel....blocked high speed jet, blocked channel or a check valve that is stuck CLOSED or perhaps a diaphragm issue.
-
I distinctly remember one MS460 and the saw had no idle but would rev OK but the idle was non existent. I suspected the check valve was shot and a new secondhand carb resolved the issue. All you say about the check valve is correct and perhaps my saying the idle was very rich may have been an overstatement but the check valve breaks the carb in to two distinctive circuits to supply fuel at high and low revs. If the check valve is stuck open, the carb will be pulling fuel through the low speed circuit and high speed circuit so by my reckoning, it will be rich and adjusting the L screw won't resolve too much because the carb wasn't designed that way. The OPs carb may have a blocked high speed jet, blocked channel or a check valve that is stuck CLOSED or perhaps a diaphragm issue. The lack of high speed revs points me to a blocked high speed circuit.

An interesting comment. You could possibly put a mark on the ignition flywheel and strobe it to see if you get any form of advance and retard when the engine is revved....assuming the engine has some sort of advance/retard device or mechanism.
-
sometimes you can push a bit of soft fuel line against the H screw hole (with the H screw removed) and if you blow and suck on the pipe, you should be able to feel the check valve popping shut and open. Most faulty check valves I have seen are stuck open making the saw run very rich at low revs so it kills the idle and pickup but the saw WILL run flat out. You must have a lack of high speed fuel and that is most likely the high speed circuit from the diaphragm chamber, through the jets and in to the check valve. Have you closely inspected the pump diaphragm? Sometimes small holes in the pump or holed sealing flaps can cause issues.

Heat is building up rather than escaping so that would make me think that the exhaust is a bit clogged up. Bear in mind I don't know much about chippers.

Very true!

Been here over a year now.

Right....I am looking at putting a TV corner shelving unit in and am wondering if any of you fellas either can make one or can supply the cut timber for me to finish. Something like this: - The spec....90 degree corner with both sides being around 60cm making the front approximately 84.8528137424cm long , thickness around 55 - 75mm thick. Wood type - I like the Indian Rosewood (Sheesham) or Mango as they have a bit going on with the grain rather than it looking a bit uniform and sterile but they are a bit exotic so Elm, Walnut or perhaps Oak if there is a bit going on with its grain but open to other suggestions. I am in Norfolk so pick up is probably easier unless you have a better idea. Just PM or discuss but will be looking for some rough pricing to start with to see if the idea holds up. Cheers

The fact it will idle and not go full tilt would lead me to think the high speed circuit is gunked up so taking the H screw out and blasting some cleaner down it may help - check the fluid is coming out of the check valve and in to the main throat/choke of the carb. If you have an ultrasonic cleaner, try giving it a good boil with all the accoutrements (H&L screws included) removed. Have you tried undoing the H screw out a few turns....it may work and after a while clean out the shyte blocking it. Aspen can sometimes purge resins in cases like this.

It is probably a Husqvarna 66.....that'll learn you

Quite likely but fear we may never know. I am pondering if he had a Robot-wars robot back in the day.....Perhaps they left it for two months and then it wouldn't start Firestorm | Robot Wars Wiki | Fandom ROBOTWARS.FANDOM.COM Firestorm (styled as FireStorm on the robot's logo and website) was the name given to a series of robots that were entered on the British TV show Robot Wars.

Also check for water in the fuel....worth a punt.

204 views and no interest - do you want this saw sorted or are you just teasing us.....you minx
-
Ah, mine was exactly the same. If memory serves me right, I think I swapped the pump over with one off a scrapper and all was good but not used it in years. Just work it through and get to the end.

133 views and no confirmation on if this is a Stihl or Husqvarna..terrible😉
-
I must have missed your post. £80 if it is a 066 Stihl................... Anyway....is this and 066 Stihl or Husqvarna 66? As far as "Not Cutting"....what happens....does the saw just die, bog or anything else? If you hold the throttle open without cutting, does the saw rev out fine or die? It may be that in the period you left the saw, a bit of dust in the carb gauze strainer dried up and pretty much blocked the thing. Was the saw working 100% right up to the last second of use before laying up or is this the old ebay...seize in a shed thing.

OOhhh, that looks a nice one. Nothing like a face full of chainsaw shyte to make you smile...not!!
-
I am glad with that, it must have been...what...8 years ago? At least I am good for something I will leave it on that positive note!

Your choice then but as I said earlier, a windowed piston will have better flow characteristics.

Mostly a business tool for networking with individuals working for other companies so you can better your employment or gauge anothers background if you are meeting for the first time to sell or purchase. Not really a platform to gain contracts from but more to see the background of someone you may be negotiating with.
