I have chainsaws and chainsaw accessories.
Lots of parts interchange.

That's the Redmax G621avs, I have the a Komatsu G650 avs. Same machine?? Prices are a bit wild. I'm in Scotland as well. forgot to mention that.Lots of parts interchange.

I'll make a video of the machine running. Maybe you or someone can tell if it's misfiring from the video. I'll change the plug tomorrow and see where we are.You might try pulling it through with the spark plug wire disconnected from the spark plug (or ign switch off if it appears it's not flooding (hydrolocking) Might give ya a hint if it's timing, firing too fast.
If it don't kick back severely with the ignition killed, check gap on the spark plug, magneto air gap and flywheel key, flywheel key's groove and I hear about some guys setting timing without using a key.
You say it started good until you added fuel, that's a hint of flooding, (hydrolocking) remove fuel, let it set day or two with the spark plug out to dry out the innards and give it a crank test.
What's the best way to clear it. Would giving the machine a good work out help clean it up some.?Likely then you have a buildup of carbon in the combustion chamber that is causing the problem.
I'm pretty sure this is a metaphor for something else entirely unrelated to chainsaws and more medical in nature. See Doctor strangelove and take one before bedtime.All that because a saw pulled the rope out of his hand? I'm in my 60's and it happens all the friggin time now.
I'm wondering if you are having trouble removing the flywheel so as to get a better look at the key??????
Does the saw pull through easier if you kill the ignition spark? (If so it's a hint that it's firing too soon)
If don't pull through easier with no spark, could be carbon build-up. (or someone purposely increased the squish maybe) Have you checked the compression?
Not lot of parts readily available for that saw so handle the dinosaur egg carefully.
Yeah, wasn't sure if it was a shear line or usy oil and shadow. My eyes aint what they used to be.I think it does, shinny line at the crank side.
