If it is just a retune, it will be the cost of a crate of beer and the courier back.......can't be fairer than that:thumbup:

Yes, it is expensive though.....£200 I believe:sneaky2:

It could simply need an idle speed adjustment, there may be crud in the internal gauze filter and the carb does have an accelerator pump so this may also be an issue.

Oh I give up, fit a washer and it will cure all the ills of the world, give world peace and make it work......not:sneaky2:

No.....No bloody washer:001_rolleyes: Read this and all will be revealed:thumbup: http://arbtalk.co.uk/forum/chainsaws/33857-whats-your-bench-today-713.html Been there, done that........T shirt, vid and etc etc!

IMO....no!

The brake handle is different as are many other parts, fuel line, Air box, rear AV etc

Seen this before, I reckon the oiler pinion is incorrect. The 357 one has a flange on it on the internal bore that locates on a shoulder on the crank. This feature stops it contacting the crank seal unlike the 346 that has no flange but has a washer. It is common for this flange to wear and this takes out the seal. Make sure the pinion is the correct part as I reckon you have a 346 one!

They are good performers and can be made to be even better. I believe Husqvarna had to de-tune the saw by sleeving the air intake on the air filter union so it wouldn't perform quite as well as the 266. Open this up and a bit of porting and they are unrecognizable This saw changed Husqvarnas positioning as a chainsaw manufacturer and the 346XP was a very worthy follow up!

Been looking at increasing the performance of a small 33cc Tanaka TCS3301 top handle in an economical way. The muffler came off, saw it was pretty chocked so managed to open up the can to find......a CAT:thumbdown: Removed it, took out the strengthening pillars, bonded them in place and reassembled the can. The lower picture shows the rebuilt "Cut and Shut" can and the removed CAT! Also gave the saw a bit of ignition advance and it goes pretty well now. It halves the modification bill and will give a significant increase in power.

The outcome of this saws modification will be moved over to my porting thread...makes interesting reading:thumbup:

The one in that poor running MS200 you had looked clean and was only when I pulled the gauze filter out, I saw it was blocked with a light transparent scum that you couldn't easy see - worth checking again.

Sounds like lack of fuel, hole in fuel line, take the h screw out and get some carb cleaner down it and pull the gauze filter out of the carb and make sure it isn't blocked, not always obvious so look at it with a magnifying glass!

Just never send me one of your saws:sneaky2:

Sometimes those carb internal gauze strainer filters look clean until you get them out and look at it against the light - it has caught me out once......and once only:lol: The little bit of crud can dry and form a scum that blocks the gauze - it stops the saw revving out properly!

Possible lack of compression - inspect the piston through the exhaust port after removing the exhaust. Other than that, it is probably fuel related - dirt in the carb internal gauze filter, holed fuel line, carb adjustment or may be the fast idle throttle lock isn't holding the throttle open correctly. Good luck

You are probably right and if there is, it may be the last we hear from the OP for a bit whilst he is enjoying hospital food in the burns unit:lol: I must do a video demonstrating the joys of checking the spark in the wrong manner!

You didn't mention to not test the spark next to the plug hole:sneaky2: The hairs on my arm have now grown back:lol: As for the eyebrows:thumbdown:

I was worrying about the walnut veneer on the serpentine top cover on the 262 plus the Queen Anne legs on it looked a little bowed:sneaky2:

That will be the lower ring end catching in the exhaust port on the downward stroke, hope no one was tryinng to port the saw:001_rolleyes: Had it on an aftermarket kit once but not as spectacular!

Bugger, I have been treating your saws for woodworm:blushing:

I have one I am willing to part with,PM me a fair price and I will make sure it is in serviceable condition and put a pic up!

Good advice Andy, you may get up to a second hand MS260 or 346XP with that money but condition is everything with purchasing used kit. The 350 Husqvarna is a good option or something like the MS250!

I had a 039 that I had in before that was partially seized and a stuck carb needle valve. It was reported that the saw had failed again but the piston looked clean and the needle was worn but OK. Swapped the needle out and the saw was set up and ran but the idle was up and down, very fidgety and then just stops. After a frustrating time messing with the carb, I fired it up, got it on idle and sprayed penetrating oil on the side of the carb and the saw died immediately, repeated on the other side and the same so the conclusion is the carb throttle valve shaft has worn and is letting in air messing with the idle. New Zama carb on order and will sort this issue. Other than that, had a Husky 41 in with no top end revs, just bogging, simple carb adjust and bingo but then on testing, it was a bag of........! The idle races and dies, top end revs high and then bogging. Pressure and vac tested - big leaks around the inlet manifold so new parts on order - I hate these little home owner saws, you do the work but how can you charge the going rate when it will write off this pensioners pride and joy:001_rolleyes: Looks like another time consuming loss maker:thumbdown:
