The choke has been off, and the carbs were just rebulit but they could have had missed something, I took it to the shop I was just running out of ideas they seem to think it might be a bad valve, but he is goiing to run some test first,

      Just now rolling over 100k miles. Been feeling some steering weirdness so I get one front wheel up in the air and push at 3 and 9 and sure enough there's some wobble. Pushing at 12 and 6 gives no play at all.
      Although I'll probably be replacing the worn part myself I need some help diagnosing what all might need to be replaced. And since I need an alignment anyway I've made a deal w/ my local Goodyear tire shop to do a pre alignment inspection and identify my bad part(s) so I can replace them before they do the job.
      When I drop the car off what specific parts should I ask them to look at? I'm sure tie rod ends but what other kind of worn parts could be causing movement on the 3-9 push test?

      I have two 2003 Suzuki Ozark 250s, both 2-wheel drive.  Last time we rode them about a year ago, the red one was not running well, didn't want to idle, backfired a lot.  The green one ran fine. 
      Fast forward...I ordered a carb kit for both of them, thinking the red one has some trash in a jet.  Both of these ATVs have had little use and I've always ran the gas out after use (put an inline cutoff valve in gas line).  I pull started the red one to verify it was still running bad.  It will start and idle, but as soon as you give it any throttle, it dies instantly.  Give it a little choke, dies instantly.  Took the carb apart and it was spotless.  Went ahead and cleaned all the holes with carb cleaner and blew everything out with compressed air.  All new jets, main jet holder, and needles.  Put it back on and nothing changed.  Starts, idles (not for a long time), but dies as soon as you give it gas.  Same happens when you put the choke on.  It does the same thing when I try to run it turned to prime on the petcock as it does in the on position.
      Not an air filter issue.  It is clean and it does the same exact thing with no filter on it.
      Thought maybe there was a float issue or maybe a damaged diaphragm, so I took the carb off the green Ozark and put it on red.  Started up and initially ran normal and revved for about 10 seconds and then started doing the same exact thing.  Starts, idles (not for a long time), but dies as soon as you give it gas.  Same happens when you put the choke on. 
      So...not the carb
      Thought maybe vacuum petcock was bad, but there's no gas in the vacuum line going from petcock to carb and gas flows freely when on prime.  I even plugged the vacuum line at both the petcock and carb end and tried to run it with valve set to prime.  Gas flows freely, but does exactly the same thing.  I unscrewed the screw at the bottom of the bowl and gas flows thru carb and out bowl drain line when petcock is set to prime.
      So, I'm assuming petcock is good?
      Checked spark plug and it wasn't fouled.  Reset gap, didn't help.  Will swap plugs between Ozarks tomorrow but I don't think that is it.
      Anyway, that he history and now you're all caught up.  Scratching my head.  Valves? These were bought at same time and have had little use.  Suggestions?
      Thanks!

      Charging issue?
      I have a 2017 Polaris Sportsman 570 EFI. Yesterday, I start the machine and it says low power (10.6-10.8). This machine is on its second battery. This is a new AGM battery with 50cca more than stock.
      Should I look at the regulator or stator?
      Thanks!!!

      I have a 1999 Sportsman  500, it was running fine, than started to lose power in the winter, I adjusted the idle screw and away I went, than a few weeks ago it died, I have found that i am flooding the engine, compression was at 70PSI and due to the compression release mech. i assume i am good as it compared to the same PSI on a 2000 sportsman 500 i have. i cannot start the atv unless i go full throttle and it starts an runs for about 30 sec than dies, again it is flooded. i ordered a new carb off ebay as i could get one for around $40. put that in same issue, i have checked the timing, (good), valves out of adjustment i adjusted to .006 still same issue, i have found the exhaust lobe and rocker arm to have some wear, i have ordered new ones, but am looking for any other input in this area as well. would the exhaust cam and rocker arm cause the engine to flood? i have used a bore scope and the piston liner has good cross hatching still? any input would be great.
