First time using this forum. Owned a Kawasaki dirt bike once, had no issues. But I picked up this 4 wheeler at an auction. They stated it ran, but only needed a battery. Well I do not believe that was all true.
Some pictures are attached. Not sure why, but the whole air filter stuff was removed. They had some small thing inserted as a make shift air filter.
I purchased a battery to try this all out. Waiting to return it and get the proper size, as it was too big for the battery box. But here is my issue I had while the battery was connected.
1 - The lights on the steering column did not come on. Not sure if they work or not.
2 - The starter solenoid seems to be bad. I have a new one on order.
3 - In the pick, there is another rusted part. Not sure what that part is or what it is used for.
4 - What is the 12v rectifier? square bodied part.
So when I hooked the battery up. Pushing the start button did nothing. Pulling the cord to try and pull start, it turned, but would never fire. I have put in a new spark plug as well, it looked worn out. With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.
I have read a few other threads and it stated something about needed the neutral light on. SOmething about a kill switch.
Any help would be appreciated.

Hey guys, any ideas would be greatly appreciated on this.
So it started a few months ago, riding with some buddies and my 400ex all of a sudden lost power. Wouldn't fire, wouldn't sputter. Towed it home, and then it fired right up. It continued this pattern for a week or two, ran perfectly for varying amounts of time, suddenly died, and would start right back up if I waited 20 mins or so.
Now we get to the next phase... I was dinking with it one day, I think I pulled the carb off and cleaned it out, (not really dirty but just to be sure) and I was trying different fuel screw adjustments. At any rate, I didn't notice much change, except obviously running a little poorer when I had the fuel screw in the wrong place. I took it on a quick ride around the block, and it was just fine. Ran awesome, had lots of power, etc. Then went around the block again and it died on me this time right as I revved it. Ever since then I haven't been able to get it to start.
Now when I turn it over, it sputters, fires a touch, but won't start. Ever. I replaced the plug, CDI, and coil, with no change. I do know that it has spark, but I don't know for certain that its big enough. After replacing these with no change I popped the carb off and tried firing it up spraying some either right into the intake. Upon doing so, it revved right up, but obviously there was no carb so it didn't stay running for long. While spraying the ether it seemed to run just like other engines I've tried spraying ether into no popping or backfiring etc. When it fired right up on the ether, I figured I must have a carb issue, so I just bought a whole new carb instead of taking the old one apart for the 800th time. When I put it in, there was no change whatsoever. Still turns over and sputters, but won't fire up.
I am completely befused, and any input would be graciously accepted. If you read through all that your a trooper, so thanks very much :)
I was riding my 400ex one day and when i shut it off to put it in the garage i tried to start it put again to drive it into the garge and it wouldnt start.I put a compression tester on it and its like 30 psi with out throttle and 0 psi WITH THROTTLE.
when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out
Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
When i try to pull start (push start/roll start) it made a not normal sound and wouldnt stay running.
If my bottom end is blow why would it still turn over fine,
Are my valves siezed or not working properly
or is my timing off causeing valves to not open in correct order with fire
PLEASE HELP all help is appreciated
