60:1 is pretty light on oil..and richer in fuel than 50:1.
Check your oilpack,theres usually a max ratio in the small print.most are 40:1 or 50:1

I ended up going with 50:1, after trying 60:1 for around 50ml of fuel but made no difference. Tried 172 main, no difference ??????????????

I felt a bit of difference though if I turn my fuel OFF it seems to run quite a lot better.

Check float again

However, if the float is that screwed up, you'd be losing fuel whenever your petcock is on.

Are you sure it was 'off' and not 'reserve'?
Some petcock use the arm to mark position,some are opposite.look close at petcock arm,is there an arrow on it on either end of arm?
If it was actually 'off' it should only run for maybe 30sec to 1min then die.
If it was actually 'res' then you may have contaminant in tank that slowly clogs petcock intake and strangles fuel supply.
Switching to res temporarily gives it a clear pickup,but it would also clog given time.when the bike is off, the vacuum subsides and releases sediment from intake.
Remove tank,sluice out.
Remove petcock,blow through from carb end with tap in both main and res positions.check intake visually for damage

Funnily enough I realized today I have been running the tank on reserve since day 1 and today I ran it on ON and then reserve, same issue. When I turn it off it runs for like 2-3 minutes and then cuts out.

If it runs noticeably better when it's almost out of fuel, it sounds like a stuck or otherwise mis-adjusted float.

I'm so sick of this float lol I am even tempted to take it somewhere to get it adjusted properly..

Could be your viton tipped float needle is just gouged or too hard to make a good seal. They're about 10 bucks a piece, worth a shot.

Do you know the exact name of my carb? I think I'll try buying one of them just to be sure because I'm going to order a 175 main too. Although I think it's OK because the needle part that gets "pressed" works fine when I used something thin to press it down it springs back up nicely.

If it has a screw lid like a bottle top,its a pwk airstriker1,if its got 2 screws on lid its pwk as2.
Its the tapered tip that matters for sealing off fuel
