Husqvarna 2T wr 250 HELP!!!????

Hi all,
So here we go.... i was supposed to go out riding today at clarence with a fella off of dbw here, and last night when i went to start the weapon it came to life briefly and then sounded like it "drowned".
I bought the bike 5 days ago and it went F*#$ing hard to say the least.
So i did what everyone should do when they get a new second hand bike dropped the gearbox oil, refilled it, and gave it a good clean down basically a minor service right!
I was reading a couple of posts on here and found the mixture screw was way out im talkin maybe 6 turns out im assuming it is standard jets, so i did what most of the things i read said to do and put it all the way in and unscrewed it 1 1/2 to 1 3/4 turns out is it too rich???? and if so WHAT THE HELL IS IT SUPPOSED TO BE ON!!!!!
I thought it was the plug but now im not sure
So now after last night and all day today i have been trying to get her going again but NO GO!!!!!
I am at my wits end now and need help as most of my bikes throughout my life have been 4T and now im screwed on what to do!!!!!!!!!!!!!!!!!!!

first thing i would be doing is ripping the plug out and checking its got a good strong spark. 2t and 4t need all the same things to run, but you dont have to give a frig about valves, Id check to see how clean and free moving the power valve is to

Would that effect starting the bike i tried to get my hands on a new plug today but to no avail. so that is my next plan, the power valve obviously handles the power band but it was going awesome before i washed and frigged with the air fuel mixture

If it ran well where the air screw was i'd go straight to the plug,super cheap has NGK to suit.Wet plug be a hassle to start. Remove the plug hold it against the head and give a kick to check for spark. Helps in a dim garage.

But i just noticed you washed it might be wet somewhere?

Start fresh, new plug check spark that'll eliminate a few things wind your mix screw roughly where it was and start it up and and wind until you smooth it out. I have had cleanish looking plugs in mine and been an knightmare to start.

Fresh plug
Choke on
Air screw 2-2.5 turns out

Fine tune the air screw once the bike is at FULL operating temperature

Never try tuning a pilot circuit at low op. temp or with stale fuel.

Also check that your carb boots aren't leaking (tighten them up)
