2005 Suzuki Ozark 250 Poor Idle

Recommended Posts

Need some help please.

My 2005 250 ozark starts, idles, and runs great for about 5 minutes. Then it wants to shut off at idle and restarts ok but won't idle. After riding it for a while longer it dosen't want to start once it shuts off.

After rebuilding the carb is when it, starts, idles, and runs great for about 5 minutes.

Fresh gas, checked the petcock for blockage.

This seems to be a common problem, any one know a fix?

Check your fuel lines for cracking, recheck float adjustment, recheck the jets and make sure you got everything good and clean. Now a good sign is to check the spark plug is it wet with gas, black looking, ect. It would help if you pulled the plug and post it's condition. There is a lot of people on here that can help the more info the better. A bad coil can cause one to shut off as the coil gets hot but I think you would be able to run it more than 5mins. Good luck!

Do the symptoms change when you play with the choke adjustment?

This carb has a strange choke system, nothing I am familiar with. I have the cable tension adjusted as slack as possible.

I rebuilt the carb. It really improved the starting and idle. It was hard to start and would not idle at all, if it shut off after riding for 10 - 20 minutes no way it would start back until it cooled. It seems to run fine now until it gets hot, then it won't idle. It ran the other day for 30 minutes, I could feather the throttle to keep it running at idle. Eventually it got to the point it would not start.

Is there something I may have missed during the rebuild

Playing with the throttle and it stays running to me is a sign of not enough gas when needed...I guess I'd redo the carb. just in case. I dont doubt your abilities, but carbs can be a bear!!

Rode until it wouldn't idle anymore, 10-15 min. Pulled the plug and it is dry and very black. The plug has about 1 hour of run time on it..

I really need this thing running; any ideas?

Getting back to a bad coil; would there be any other symptoms other than not wanting to idle.

This thing does not really have a choke, it has a brass plunger. Not sure how it works!

Also has a vacuum operated petcock i am not familiar with.

How to Read Spark Plug Colors (written by Atlantic Jet Sports)

In General: Reading spark plugs can be a valuable tuning aid. By examining the spark plug insulator color, an experienced personal watercraft engine tuner can determine valuable information about the engine's overall operating condition.

Normal: Grey to Light Golden-Brown Color

This condition is ideal, the spark plug and engine air/fuel mixture are operating properly.

Dry: Black Soot Buildup

Air/fuel mixture is too rich, the carburetor settings are incorrect, or the flame arrestor is dirty or has mounting problems.

Spark plug heat range is too cold for the operating conditions.

Ignition system problems causing a weak or intermittent spark.

Wet Fouling: Shiny, Wet, Black Appearance

Excessive use of the choke (gas fouled)

Prolonged low rpm operation (gas or oil fouled)

Fuel to oil ratio is too rich (oil fouled)

Excess Deposits: Bumpy, Chalky Buildup

Poor fuel quality

Oil leakage into combustion chamber

Improper oil used for premix/injected

Overheated: White, Blistered, Melted Electrode

Lean air/fuel mixture

Spark plug heat range is too hot for operating condition of the engine

Plug is not properly gapped and/or torqued onto head

Overly advanced timing

A detonation problem would show signs, such as silver specs, black specs, or melting or breakage at the firing tip.

NOTE: Signs of fouling or excessive heat must be traced quickly to prevent further deterioration of performance and to prevent possible engine damage.

See what you all think about this.

When I purchased this thing it would hardly start or run, kept flooding out.

Adjusted the valves and rebuilt the carb; started, ran, and idled perfectly; until it got hot.

After inspecting the coil , I decided to check the oil level. The oil had a lot of fuel in it, so I changed it. Since changing the oil this thing runs perfectly.

Do you suppose it was starting to seize up when it got hot and that is why it would quit ideling?

      So this '02 Taurus with only 87k miles on her starts right up every time multiple times a day except for twice in the last 3 weeks. The first time was 3 weeks ago and the second was today. It happened the same both times. Turn the key and stop to let the pump prime, then when I turn to the start position the engine turns real slow and sort of in fits. Usually when a battery is low the engine turns slow but in rhythm. During my 2 starts the engine barely seemed to turn and the crankshaft rpm seemed to vary. On both starting events I let off the key and tried to start 2-3 times with rests in between. But then eventually on the 4th try it starts right up just as quickly as a normal start.

      I have No clue as to what might be causing this. Only thing I know to do is, next time it does this to put a voltage meter on the battery to see if it's weak. Actually though, because both events the engine ended up starting up like normal that would indicate something other than the batt. Electrically this car is a little odd though. The interior light never comes on when the doors are opened, for years, and then last week it comes on twice when one of the rear doors is opened.

      Well I will be Off the Trails for awhile...who will be riding ??
      I said awhile ago that we would be done for awhile,and we made it back out,but now I know we are off for at least two weekends,Wife is on Call.
      and I might send mine out for some due repairs,that I do not want to do because of the timing,and that I have not done them before.
      I need new brakes,front and rear!
      and A Chain and Gears.
      Deer Season is Nov.15th thru Nov.29th so no riding during that.
      And we need to clean the Garages to get the daily drivers out of the snow,and cold weather.
      So I hope that others step up and get in some riding while we are down.

      Was using the quad the other day to shuttle wood from my pickup to my wood pile.  When the job was done I turned off the Quad and heard a bit of a racket from the front end.  When I got down underneath the sound seemed to be coming from the fan housing.  fan was moving in spurts and not quickly... much like a computer case fan that's had it's day.  What I know.
      Temp sensor is ok, as the fan tries to activate fan is getting some voltage as it is attempting to spin.  When I first bought it used I tested the fan direct to battery and it was fine. The fan was working ok even not direct wired as I went on a couple of rides and when stopped and idling the fan did run Seems to be free spinning with my finger read up in the manual and they require me to drop the rad.  now I'm not opposed to that as the rad has some damaged areas I want to try and straighten out.  But if I can get the fan working without, I can leave the rad as it is until next year.
      Fan assembly is about 300 bills, any work arounds or alternatives?  I even thought large computer case brushless fan.  smaller ones are about $7 larger ones better quality probably far below the 300.  They run standard 12v DC.
      Anything I should be doing before dropping the rad... other than check for obstructions even though it seems to spin, and trying to hardwire it to the battery again for a test to see if it acts the same?
