1999 Suzuki King Quad 300 - Floods~Won't Start


Recommended Posts

I went to start my '99 King Quad today and it fired up and ran rough, very rich.

It's cold out so I wasn't surprised and figured it would warm up and run smooth like it usually does. It's been running a little rich but is fine once it warms up.

Instead of warming up though it died. I couldn't get it restarted so I took it down to the garage and pulled the spark plug, it was covered in gas.

So I let it dry out and tried starting it again. It wouldn't fire and the plug was soaked again.

I took the carb off, cleaned it, took the bowl off and sprayed it all down. Didn't see anything out of the ordinary but I couldn't get the float out to check the needle.

I put it all back together and got the same results; the spark plug gets soaking wet.

So it seems to me that either the float has a hole in it (but the float wasn't full of gas when I took the carb apart) and is sinking or the float needle is not sealing (this is what I suspect) and gas is just pouring into the bowl.

Am I on the right track here?

It looks like the shaft that holds the float on is peened over on the end opposite the end that has a head on it, is that correct? I wasn't able to just pull it out as I'm used to doing. Any tips on getting the float out would be great.

Thanks for the help!

Do you know for sure you are getting spark? This almost sounds like an ignition problem to me.

If the float had a hole in it, it would be full of fuel, and if the needle was stuck open I would think that the carb would overflow with fuel and spill into the engine. If that is the case, you would have a lot of fuel in the oil or at least on top of the piston. If you tried to start it in that case it would hydro-lock and likely bend a rod. Next time you try to start it, pull the plug, try turning it over and see if fuel shoots out of the spark plug hole.

Did you check the float height adjustment? It should be about 1/2" or level with the flat part on the aluminum body where the cover mounts. You can check if the needle is seating properly by blowing into the inlet (make sure its clean) and moving the float up and down to see where in the travel it closes (blocks you from blowing air). If it never closes or closes way too low, then you have your answer.

I just had mine apart but never tried to remove the float, so I dont know what the pin looks like. Sorry. But I found a float kit on ebay and the pin just looks straight on that end. I dont know why it would be peened over...

I better check for spark before going any further.

Last winter I spent countless hours checking over the fuel system on my car because it was flooding, finally I took it to the shop and it turned out to be the cap was burned and creating a weak spark.

I do not seem to have fuel pouring into the cylinder but I will get a closer look, it definitely isn't coming out the carb overflow.

Thanks for the tip.

I had the same prob. Lots of fuel but wouldn't start.

You may be digging too deep.

How did you check for spark?

I just solved the starting prob.

Pulled the plug and grounded it against the engine.

No spark. I put in a new plug and she starts right up.

      I just bought a 91 and when I went to change the oil in the rear diff it had water in it (milky oil). There are no leaks in the seals so I think it's coming in the vent tube. Thing is I can't find it. Anyone know where it is. 
       
      Thanks

      OK, sooo  I finally did the old skid plate and screen removal to clean out my oil sump during an oil change...  This bike only has a couple thousand miles on it.  Runs like a top still...  Very few issues over the years after buying it used.
      But boy I wasn't expecting to see this!  Piece of a circlip, stuck up in the screen, and a another shard of metal and maybe a piece of gasket material.  Nothing in the oil but that...  Pristine otherwise, and still runs like a top.  Always has.
      Soooo, is it a wrist pin clip?  That's the only thing I can think of like this that could end up in there.  But definitely wanted to throw it out to guys that have seen the innerds of these more than I have.
      The valves on this thing are still within the factory spec even.  Been a really good lil workhorse...
      Any other ideas?

      Hello everyone, i have 2000 Polaris Trail Blazer 300 I’ve been stumped on for weeks. I’m having a lot of issues starting the quad. I cleaned the carb spotless because I thought it was a carb issue and bought a new fuel line because it wasn’t getting fuel. The carb gets fuel perfectly fine now but it won’t start. The spark plug I a little worn out but it’s good enough for just one start. The only time it does “start” is when I spray starter fluid into the carb. But it never stays on. It’ll start for a bout a second then just die out immediately even if you’re giving it some throttle and the choke is on. I have no clue what I should do. If you need more information, have questions, or have any slight idea what the issue would be and how I could resolve it. Please reply ASAP. Thank you.

      I have a problem with my trx. One day it was running fine, but the next day it didnt start. It ran for a little but didnt want to start after. I think it might be an electrical problem. Usually when i pull the crank, the headlight and neutral light flash with it. Now when i try starting it, they dont flash. Could be the spark plug, but please help, thanks.

      So here's one I haven't beat yet, could use some input. Honda 300FW was running fine when one day it started bogging at WOT. Figured dirty carb so I cleaned it and still the same. Cleaned again once more by soaking overnight in thinner and then compressed air. Back together tonight and still falling at WOT. Tried a known good plug...nothing makes sense here. The float bowl does seap a bit due to old gasket, could it draw vacuum enough to interrupt fuel?

      Hi Everyone,
      I am new to this forum and hope that someone out there can help me, I have an early Suzuki King Quad 300 (280cc) which starts intstantly every time but at about half revs or there abouts it starts spluttering and will not rev any higher, this fault is present whether choke is applied or not, some one suggested that silencer maybe be clogged so removed baffle but no improvement have removed carb and stripped 3 times but still no joy.
      Any ideas would be most welcome.
      Cheers Rob
