Yup, Rowena are the go to carb specialists. Hugo is da man and very helpful.

No, net easy to fit and very easy to cock it up and at £12.50, easy to lose your money. Getting the old one out, pierce it with an awl at an acute angle ( protects damaging the cage) and lever it out. I clean the area, use plenty of oil, push it in as far as you can and tap it in to place with a suitable deep socket. I do use the factory guide to ease the seal around the inner race which makes it much easier. I guess I have done around 25 -35 on 550/560/562 and 346s in my time....so you can gauge the worth of my comments.

There wasn't really too much wrong with the physical build, more the ignition timing, carburetion and exhaust design. There aren't too many issues now, the mufflers crack in the middle of the base but the rest of it seems pretty sorted now.

That's Brad Snelling me old mucker👍

The AT would try to keep the revs down and would succeed unless the air leak became too big for it to do this. If you get a CST read out from the AT, you will be able to look at what the carb is doing at high revs.

Did the "good carb" have a different solenoid fitted or the same one,? If it isn't the solenoid, it is probably one of the wires broken or the sheath worn where they enter the saw from the handle.

Yes, the first ones were absolute Shyte but the Mtronic ones are far better. The MS200 always benefits from a lot of grunt from low revs, the Mtronic MS201 doesn't have that but it does pull well once the revs are up....I know from porting both saws and doing timed cuts. It was close but the 200 still has it.

Thanks for the update....I think. Yup, loose ends are never good but in your case.....😬 I hope you find a more reliable way to cut wood...perhaps a trained, tame woodworm👍 I would say beaver but on a Saturday night, this lot may get excited!!

I think it may be Mendiplogs from his spelling...sorry Jon if you are reading.

Follow the money, who and how would you pay the tax fee to. If it is the courier that is shipping the kit, chances your boy has fooked up..perhaps paid by PayPal and the authorised address was used? If the recipient of the payment is a bit suss, grey, unknown then don't pay. These days you get reams of notifications on delivery...from the seller and courier then review sites etc...what has your son got?

"Virgin"...I guess it hasn't done any chopping yet🤔 Should be Virginia I would think.

You must have a shipment number so that should tell you where it has come from. If the duty is paid directly to USP then I can't see how a scammer will get the funds, it is usually a dodgy link, false web site etc. If you don't pay it, the parcel will go back to the US. You could enquire who the sender is.

Strange, the ferrous stuff that thin are bearing cages, small end cage, circlips and muffler/ baffles. Not sure what else it can be...any helicoils on the top end? I did once get a 346 in that had destroyed three top ends and found the big end cage was the offender. The owner had missed it completely.

Try pulling the seals on the crank bearings first, they may tell a story although the flywheel side may not give you much of a view....not done many 61s...ADW would probably have a bit more experience on these. Looking at the bearing through the open part of of the crank lobes may also help but can't really see the metal being anything else than the main bearing cage. I had similar on MattyFs 560xp many years ago, one of the stuffers had disintegrated causing similar damage. I managed to grind the port damage out, a good friend machined a pop up and took the base of the cylinder down and it worked on for a few years before detonating.

I have never found the need to pull welch plugs and my advice is not to as they are damn difficult to seal up correctly and permanently. I have had just a very few carbs that have gone bad and have not responded to a clean, carb kit, check valve, reseal of welch plugs or new accelerator pump. The 020t carb was one that would go temperamental with unstable idle and not respond to any normal fixes. It depends what the carb is off and what the issue is as to what action I took. Some have non serviceable accelerator pumps...the 357 springs to mind.
