Hey there everyone! Snow is great outside and I really want to go out for a ride on my sled! Been trying to get this fixed for weeks but no luck so far. Any help on what I should do would be greatly appreciated! I've tried reading up on this forum and tried a lot of things before posting.
My sled is a John Deere Trailfire 82, and it's been working great for the past few years without much trouble. I changed the coil and battery last year and it's been a really easy start since then, until a few weeks ago.
What happened:
I was out riding and I accidentally emptied my gas tank completely, I was going downhill so it drove for about 20 meters after the engine stopped too (I don't know if that matters). I refilled the tank but after that it wouldn't start at all, no ignition spark what so ever.
What I've tried
Some more details & random thoughts:
(I'm a real beginner with engines so I don't really know what I'm doing)
* I'm 100% of where the mixture screw was, but I'm not completely certain about the idling screw. Could that be the problem and how can I know where it should be? I've tried a lot of different tries with variations of where I think it was before
* Sometimes the spark plugs get a bit wet, then I pull the string a few times to dry it out. It does feel like the left spark is abit dryer than the right one.
* When no spark plugs are in and I pull the string, I usually see a puff of smoke on the left (dryer) side, but not as much on the right. Could that be something?
* The gas is all new, but when I look into the tank with a lamp I do see some small sparkling things in the gas, could that be some kind of dirt?
* When I cleaned the pipes I used compressed air, could I have damaged the gas filter?
* Maybe I didn't clean the carb well enough? I could see through all the jets and I felt I did a thorough job but I don't know.

What I've tried
- First I tried starting with a little starting gas (spray can), and when I turned the idling screw a little to the right, it started and I drove about 1km. Next time I tried it didn't want to start at all.
- I tried cleaning the fuel pipes with compressed air. A few tries later it started again and I could ride it for a few kilometers, but it didn't feel as strong as it has been before, it went worse and worse and finally stopped, and then it didn't want to start again.
- A few tries later it did start but ran very badly and died several times. Here is a video of how it was running:
- After some research I cleaned the carb, it did run but pretty much the same way. I also tried changing the spark plugs. I tried changing the idling screw a bit forward and back but couldn't notice much change. I also tried adjusting the other screw a bit (mixture screw?), but not much change there either.
Here is a video of how it's running now:
