Put new flywheel on and still no luck not as much fuel now but still over reving 

Dicked about a bit more and now running a lot better

What actually happens when you lean the H screw off? It just sounds like if you screwed the H screw in it would rev out properly and reduce the blow back, the H screw in the first video looks a long way out?

That's what I said last night!

The standard settings are 1 turn out but if they are set to 1 1/4 turns each, the saw should run fine once the idle is adjusted. 

I have only ever had fuel vapour coming out of the carb when the carb is megga rich or the piston skirt is very worn and the pressure in the lower crankcase freeports past the sealing piston skirt back up the inlet port and out of the carb - that was a ported MS660, ran fine before modding but the squaring of the inlet port caused this issue but a new piston fixed it. It appeared the saw had been used for a lot of milling and the filter was pretty worn causing the original piston skirt to wear.

If it's a genuine New carb with factory settings then I would check that the ht lead/coil isnt shorting out somewhere. I've seen it on other machines. Ok at low revs but shorts out when you increase them, it acts like a rev limiter.

I've just downloaded and watched your recent video. Probably not the ignition like I suggested. Worth a check over but it does sound like a fueling issue as already mentioned by others.

Metering arm stuck down ?

If it was stuck down, the saw would flood and not start. The fella has "fitted a new carb" so it can't be the carb....unless "New" was in fact "different" or "cheap Chinese poop"!

Time will tell.
