I have video that I can send via text or email. But basically the only way I can get it to even start is to hold the throttle wide open, and then it doesn't even come close to revving up. It mostly just pops and doesn't sound good at all. I'm kind of unsure of where I should even start, I'm not an expert by any means but I know that what's going on isn't how it's supposed to run. Like I said, I'm not sure how to describe it all that well but I have video that can help you understand what's going on as far as sound etc.

ok, when was the last time you cleaned the carb?
HOW long does this atv sit between being used, IF over a month or so
MY suggestion is this
DRAIN fuel, inspect tank, MAKE sure its CLEAN
then clean/rebuild carb
if you clean carb and have a dirty tank, as soon as you run fuel back into carb, you can have a dirty carb again, thus why I said, START a new, new FRESH fuel(non ethanol all the better) then clean carb
check and inspect your choke cable, and make sure its working properly, a stuck chom=ke can happen and cause both starting and running issue's
as can a stuck float flooding your motor

NOW< that I said that, ITS time to check your OIL and SMELL it
if it smells like fuel, you have a carb problem and most likely a stuck float
Having fuel/gas in your oil is BAD< you need to fix this ASAP< and or at least, shut fuel peacock OFF< drain carb bowl, and then change oil and oil filter!

fuel in your motor will make seals and things go dry and or rust, causing failures and bigger issues for you!

NOW< IF your carb is 100% correct, fuel in GREAT and fresh

you can have other issue's,
from jumped time, to a BAD CDI, low compression, , even a BAD spark plug(easy one to fix, and won;t hurt if you put a new one in gaped right, and inspect the old one and see what it says(tells you by looking at its color)

OR post a pic of it here?

but the above is all good places to start here for you, and not so hard to do

A flat track TT 400ex. Dont see many of those. One thing that wasnt mentioned above is trying to spray some starting fluid into the intake and see if it fires without the throttle held wide open. If it does it tells you its a fuel delivery issue. If it dosnt then the more internal options are more likely. Skipped timing, low compression, sheered flywheel key, or something along those lines. At that point your gunna have to go internal. My .02 welcome to the forums!

I'm gonna try to get it loaded up either tomorrow night or Thursday night after work and bring it home to the garage. From there I'll give that a shot first thing and let you know.
