Havent had a chance to look far but, with no line in it, I.E no load, it starts ok but when the throttle lock comes off and I give it some throttle it just dies, seems to idle ok, removed air cleaner, made no diff. Might put some fresh fuel in it. Will update tommorrow.

Guy I work with had this problem. Something to do with a rubber mount at the base of the engine Where the drive shaft run though.

blocked main jet in the carb, take the carb apart & clean it out. If you are not keen to do that try just removing the high speed mixture adjustment needle, blow down the hole, pull the cord, etc & that might clear it.

Blocked air inlet on fuel tank, recently had that same issue on my baby stihl saw, was about to put a kit in carb, but not needed since cleaning it. A symptom i noticed at same time, was primer bulb was not filling and pumping properly.

the primmer bulb some times gets a fine crack in it so just replace that and try again

Don't go pulling the carb to bits yet, without doing the simple stuff first. As #2, check the spark arrestor screen first. Very common issue, and an easy fix. Get access to it by taking apart the muffler, or undoing the 15mm (from memory) exhaust outlet, depending what model it is, pull the mesh screen out or if it's a small cylindrical shaped one on your model, attached to the rear of the small exhaust outlet, put it in a vice by the nut and twist the silly thing off with pliers.
Then if it still doesn't go, you start thinking about carb issues.
Most stihl agents will remove those arrestors at the first service. Pain in the arse.
If you really want to keep the screen in there, verify that it is the problem by starting the machine without it in place. If it needs cleaning, the easiest way is to burn the carbon off with a propane torch, then hit it with an air gun to blow it out. Or you could use a wire wheel on a grinder.

had the trouble with the spark arrestor, removed that a while ago, will look at the feed from tank to carb, i would think definiterly a fuel issue.

Well so far it looks like you should: remove the spark arrestor Shaft drive rubber mount main jet high speed mixture adjustment fuel tank air inlet Primer bulb
There isnt much else to replace other than the whole chainsaw

Update went out this morning gave a couple of pulls on the rope, did 10 min work with it, good as gold. could have been the fact that it was sunday and it didnt want to go, lol, but could have been a bit of dirt somewhere, all good now.

Its allowing you to develop a false sense of security before its crank bearing disentigrates and it spits needle rollers out the pipe, devious little bastids, you can't take your eye off them.

Sounds like the low speed screw may need adjustment. It should be 1 turn out from memory and then adjust from there.

Yes, fresh fuel. Tip the mix into a container and put it in your car. If it was a 4-stroke mower, you'd need to rather drain it with a siphon it before putting it in your car, otherwise the oil engine and gravity become inverted when you tip the machine over.

I am wondering at the logic of taking stale fuel out of a machine that cost a few hundred dollars and feeding it to one that cost (probably) tens of thousands? To save maybe $1 worth of fuel?

Those Mason wasp's are quite keen to move into small engine mufflers . Hard for an engine to run if they cannot breath .
