1999 Suzuki King Quad lt-F300F Hard to start

Recommended Posts

Hello

Just signed up, as I've had a recurring problem, and need some help.

To start the bike I have to put the choke on all the way and 4 squeezes on the gas, Then as I push the start, I slow squeeze the throttle about half way for it to catch....If I miss it, then it will take 5 mins of slowly finding the sweetspot on the choke in unison with some throttle squeezes.

Then I have to to hold the throttle to keep the bike going, using the choke will stall it out. after about 3 mins of holding the throttle, I then can let it go, and it idles fine, and runs fine. If it sits for a few hours it's only slightly hard to start, but a few days of sitting, and it's a lot more work.

Had the bike serviced they couldn't figure it out. They swapped peticock, plug, new gas, all new lines, new throttle, and cable. Said the carb was fine, and clean. New air filter, said fuel pump was fine, no leaks around carb boots, new battery, new rectifier.

Ran some sea foam through it....Runs Great.....Just such a pain to start...

Thanks

Hello

Did a lot of reading on this site, and have had some good luck. I shortened up the vacume line from the petcock to the carb, and discovered a small leak in the crankcase where it comes together. The gasket must be gone if it has one there.

Used some chemical resistant cement to seal all along the seam, and snugged all the crankcase bolts. The leak was a drop every 2 days or so. And now it starts up everytime, but I have to keep giving it throttle for about 3 minutes, then it will idle on it's own. When I try to give it a little bit of choke to keep it idling, it just floods it, and it will quit.

So now the bike starts fine, but I have to nurse the throttle for 3minutes to get it to idle on it's own, while applying the choke will kill it.....

Any thoughts...?

Thanks

I ended up replacing the vacuum petcock with a manual and replacing the fuel pump on mine with a cheap honda one. I dont trust vacuum petcocks, they are always a source of mystery running problems on older bikes.

maybe your floats need adjusted? bad float needle or seat? I know the shop said they were ok but it obviously isnt running right.

      I bought a used 2017 Outty 1000r and have been hearing about folks melting plastics due to excessive heat near the pipe.
      It's winter here & I've been plowing my drive for a couple months without heat issues. I'd like any input if this will be a problem come summer?!?
      TIA

      I'm joining to get help and opinions on my z... I just had the entire bottom end and carb rebuilt new rings and plug rose it maybe 4 hours and on the way home it backfired and blew the carb boot from the head and now it won't start? Getting fuel and fire but when I check the plug its covered in fuel? I've checked time and clearance everything seems to be fine? Just cant figure it out?

      Hello - I have just had delivered my 2004 registered King Quad 300.
      The gear change is pretty fierce.  Pretty hard to get into gear from neutral on the foot pedal and when I select reverse on the hand lever, it jumps into reverse with a hell of a kick.
      I am waiting for a service manual to arrive, but in the meantime, has anyone any suggestions please?
      Thank you.

      Take a look at this. I just ordered it. Wondering what your thoughts are ? I mainly like to get my bikes up In the air so I’m not killing my back any more.  I either build up some stuff I have laying around etc but this looks like it’s going to work out well.

      I have just ordered a Suzuki King Quad 300 which should be here this week - it is described as "with slow running needing attention"  I am as a matter of course going to put a new spark plug in, change the oil and oil filter and blow out the air filter with compressed air - anything else I should consider?  Also, the headlights do not work - I want to change them out for LED ones anyway though.

      I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?

      Feul pump went out. Replaced. At times quad cuts out like its not getting gas. Saw article on new pump needs to be calibrated. Told how to go into a service mode. Does not tell how to calibrate after going into mode. Can anyone shed light on this procedure.

      I have an 04 ltz and it started sputtering a little bit while going down the road and I was low on gas so I just figured that's what it was. But now I can't get it to start I completely cleaned the carberator put a new spark plug and coil pack in it and all it does is turn over. It has compression it's getting fuel and it is sparking but all it does is turn over any idea what it is??
    • By izzydum1
      Any ideas on what would make a coil not fire? She was running fine, then began slow start. Now wont start at all.
