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?

posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
Hi bought a 2012 kingquad ASI last year a great machine which is a delight to ride, but I find sometimes it doesn’t go into top gear just revs high at about 42mph. Any idea ???

Its in pretty rough shape and its gonna be my first atv, I worked on bikes before but nothing to do with quads. Anyways the quad has some problems and im tryna figure out what to focus on first. So the U joints i think are shot. The bike starts first try every time ussually have to give it a lil gas with the throttle and revs right up, idles fine but its running REALLY rich 3 starts and my brand new plug was pitch black
Bike is L model
Its using the original mikuni carb but im not the best at fixing the carbs and wondering if there is anywhere online that would be able to either walk me through it or help me with it i didnt see a air mixture screw so it seems like im gonna half to open it up and adjust like the float and a couple other things

We had a few days of rain & then a cold front came thru our area. The claimed we had snow in the mountains, so I went for a ride to see for myself ... and what did I find ?? ........... SNOW !! ......... Not a lot mind you, but it was fun. When I unloaded the bike the temps were 27 degs F (-2.7c) & warmed up all the way to 33 degs F (0.5c) ... for about an hour. The rest of the day the temps stayed at 31 degs F (-0.5c) ... and then the storm came in ........ WOO HOO !!
I will say however, there was no dust or bugs !! I did see a few people as the muzzle loader deer hunt was on & I think I was the only one that saw a buck !! ...
Saw a few other deer & then a family of Mooses ... a cow & calf & a nice bull !! I got as close as I dared, making sure there were at least a couple trees between him & I & took what photo's I could ....
Here's a short video of the days ride, make sure you watch it in 1080p & I hope you enjoy it !!

Got the tracks put on the Outty & decided to run up to the mountains today to check out the snow conditions, do some more testing of the Drift GHOST HD Helmet Camera I just got, test out some of the camera mounts I put on my helmet, and a few other things.
The day was overcast, temps were cool at 23 deg F with winds 40 to 50 mph and light snow. It was GREAT !! :woot:
I took some video in 1080p, 960p, WVGA & the majority in 720p. After looking at them when I returned home, to me, the 960 & 720p looked the best.
I added two camera mounts to my helmet. One is on the side of the face shield & the videos with the camera there are pretty good with not much helmet in them.
The other mount is on top of the helmet & you get an “Overall” view. Not sure which location I like better.
Both mounts are stick-on with 3M sticky stuff, they seem to hold real well … however, I was walking thru the trees to take some photo’s, a branch hit the mount glued to the side of the face shield & popped that camera off like it wasn’t even glued. I’m sure the cold temps didn’t help either.
I also took some video with one of my older HD170 cameras. The exposure setting on both the HD170 & the GHOST were set at zero … and you’ll see that the HD170 is much darker. So on overcast days, I’ll have to remember to set that camera at +1.
I must’ve hit the remote too many times at some point today too, because I had 177 photo’s instead of video. Dang it, that means I’m gonna have to re-read the instructions ……….. again ….
Here’s a short video of today’s ride, hope you enjoy it …
