I've had this machine for 2ish years, has ran great up until winter. Sometime during then, I managed to break the exhaust right before the muffler. The summer before it had a hard time idling, but we fixed it by cleaning the carb, and messing with idle. Near the end of last year, the only way for it to fire was the have full choke, and full throttle, and the engine bogged down and you had to keep on throttle for 25mins. Over winter, the throttle had dislocated, and I got it back in place. We got it running, and all was good. Spring came along, and now it doesn't start at all. A fluid is coming out of the exhaust, and I'm told it could be water from over winter. I checked the airbox, and the air filter isn't for this quad, it also is barely sucking air. There appears to be little to no compression, based on this. I'm pretty sure the engine is flooded, as the spark plug produces a spark, but is oxidized. I don't know how the previous owner treated it, or when it's last oil change was. A bolt on the engine has either oil or gas seeping through it,abd was loose. I tightened it and it consisted. The engine is basically positioned in the rear, and it needs a good clean, I don't have a pressure washer, so I can get the built on dirt off. any recommendations on how to get the beast started again?

All I have been through everything. Bought brand new.
Throttle safety switch
Cam and rockers
Fuel safety switch
Everything every forum has spoken of I've bought sealed airbox completely tight unplugged black wire on trans. I have literally done everything in the book.Checked oil today full of gas anyone no anything what might b wrong. Next I'm taking head off and making sure valves seat any ideas.
Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.
What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.
Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
Thanks in advance.

I just recently bought a 1994 Yamaha Timberwolf 4x4 from a buddy who had the wheeler sitting in his garage for 7 years. I got it home and fired it up pushed it out of the garage and tried to shift it and it wouldn't shift. First it would click like it was shifting, but the wheeler wouldn't move and when I hit the gas it revved up like I was in nuetral. After trying some more it became stuck in 1st gear and wouldnt shift at all. But it later broke loose agian and acts like it is in neutral again. I took the motor off the machine to make it easier to work on.After asking friends they were convinced it was a clutch problem but after opening up the casing for the clutch I don't see anything out of the ordinary and am concerned that it may be a transmission problem. Any help would be greatly appreciated thank you.
Have a 2002 Polaris Sportsman 700 that only has 34mi. on a carb & ring job.
Cut the gas off today to drain carb.Now engine will not idle.If I open throttle will run,but let off & will cut off.Can screw idle in with no change.
What happened? Why did this happen when fuel ran out?
Please help me,my ATV is a daily driver.
Looking forward to posting some questions on here, doing some reading on here, and enjoying the company of others.
So I bought a 1994 Yamaha Big Bear 350 4x4 from a buddy of mine for $1,000. He has had the ATV for about 2 year. No rear problems when talking about the motor. It has failed to start some, and unfortunately it does not have a pull string. Not sure if that is something I can add on later or not. But we traced the issues to the starter and replaced it. Now it starts easily and has a new battery and starter that he bought .
Issues I am going to be working on, and asking questions about:
Hours display is broken and doesn't show anything at all
Would like to possibly add a speedometer at some point
Rear brake doesn't work until the pedal is all the way down to the floor, and then it engages, doesn't really brake. I'm thinking this is a simple adjustment
ATV pops and clicks when turning. Was thinking CV axles, but not sure and want to be 100% sure before I order replacement parts
Need to learn the braking system better. It has two hand brakes and then the pedal brake. What's the difference and how do they all work together. Assume one is a hybrid brake that engages both front and rear at the same time, but not sure
Need to clean/paint the hubs
The shifting is tough and some times requires more pressure than I'm comfortable with. Not sure if it's lubrication, or an issue with the linkage. Need to learn that too.
Having a hard time finding a manual online, need to buy one probably
I have around $500 to invest into the ATV. I am hoping this will take it back to really nice riding condition.
Any thoughts on the above issues/concerns? I plan on using the search functions as well.
Looking forward to hearing from you all.
Does anyone on here have a 2013 honda rancher? I have had several Honda ranchers in the past but I bought this 2013 rancher and it hits the rev limiter at half throttle. It is very annoying and I was wondering if anyone else's Rancher does this. If this is something from the factory or if I have a problem or not just trying to figure it out. Any help would be appreciated
