Picked up an LT80 (unknown year) for $200 recently for my girls. Not running at the moment, but does turn over. I’m thinking the carb needs to be rebuilt or replaced, as it appears to be leaking 2 stroke oil. Anyway, I’m excited to have something to wrench on in my (limited) spare time

So I’ve had this quad for the better part of a month, and it’s been hard to start since the day I bought it. Once it warms up it idles just fine and has plenty of power and starts no problem, but cold it takes 20 seconds minimum of straight cranking to start it.
It’s not really too big of an issue, I’m just curious as to why it takes so long. Earlier today, it took me about 2 minutes of on/off cranking to get it to fire.
i have attached a video of a cold start to show you what I mean.

Ran find shut down the quad next day would start and idle when you try to accelerate it would start popping through the carb got a rebuild kit soaked it in chem clean after break down for 12 hours on slow vibrate reassembled and adjusted per manual still the same thing any help would be really appreciated thanks and happy ridding

1987 YFM350FWTB 350 4x4 Big Bear when going uphill will sometimes act like the clutch realeases then re-engauge all at once.
Seems to maybe be little more often if the engine is at about 1/2 throttle instead of at lower rpms.
I have the Factory Service manual and checked the external clutch adjustment screw as ok and the H/L/reverse shifter lever linkage as adjusted correctly. It appears to be maybe a internal (inside the case) clutch issue or ??
This is the type Big Bear that has the manual shift lever on the left front fender and has the manual foot shifter lever with 5 speeds forward.
Can someone tell me how the primary and secondary clutch operates?
I assume one is mechanical and one is centrifugal. (what I'm asking is one clutch for the higher rpms and one for the lower rpms or ???. (the clutch appears to only momentarily release at the higher rpms is why I ask. The cycle has about 3000 miles of low speed through the brush hunting and has been well maintained, oil changed, etc and no deep water or mud useage.
Anyone been into a similar issue with the big Bear ATV????
got 7 atvs off CL recently for a good price. one of which is a yamaha warrior. anyone know where the vin is printed on this bike? Haha good place to start as I do not know year or size yet. The former owner says needs exhaust ans and clutch work. he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears. things I see: clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box. I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first. also, battery (looks brand new, what a shame) is dead, 0 volts. Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last). any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like. lol I'm spoiled on my automatic polaris
