Hello everyone I am new to the forum. I am working a Suzuki King Quad 300 4X4 for a family member and I am dealing with several issues. First the atv has been in storage for several years. I had to buy a used fuel petcock for it and install it. It works great and the fuel pump is pumping fuel just fine. The atv has great spark no issues there. I pulled the carb off initially and cleaned it. The problem I am having is the King Quad is hard to start. I put in a new battery and it would take at least 2-3 minutes to start! Once I got it running it ran fine. Yesterday I removed the carb again and cleaned everything again and it is worse now. I had to turn the idle screw in the whole way for it to idle. Now it won't start or run unless I take the boot off between the carb and air box. And when you hit the top end of the throttle range it smokes really bad. I checked the intake boot and it does have some cracks in it but I sprayed starter fluid around it and nothing happened? I am not sure if the cracked intake boot would cause the carb to no operate properly or not? I tore the carb completely apart and cleaned all of the jets, air jets and made sure all carb passages were completely cleaned. I adjust the air/fuel mixture screw out 1.5 turns and tried it at 2 turns it didn't seen to make a difference in operation. I tried several times to reinstall the boot between the air box and carb and it shuts off immediately every time. I checked the air box, screen, and air intake tube for any obstructions and I did not find anything. I checked the choke function and it is working properly. I also double checked the jet placement and made sure I didn't switch the choke and main jet, no problems there. So I am at a lose now and need help desperately. I did check the air filter it is fine too. A local motorcycle mechanic said the intake boot has to be the culprit but before buying another one I need to find out if anyone else has suggestions on the matter. Thanks in advance for all of your help!

Hello all, new guy in the forum here. Just wanted to tell you all there is a plethora of information available on here, that is well organized. I have been working on my Uncles King Quad. My first dealings with an ATV top end rebuild. What I have gleaned from this site in the past few days is incredibly informative and detailed. Just this particular thread has been great! Thanks for sharing the info and have a cold one on Roguesman!
Just about to order new regulator for a 96 KQ 300.
Thanks to all contributors here on these forums. Especially thanks for posting what fixed your problems not just fixing these then running off leaving people in the dark like happens on so many other forums.
Thanks,
Stevie

Greetings, I am new to this forum / and quad owner. I have purchased 2 1991 King Quads( LT-F4WDX by Original Paperwork). These 2 beasts have sat in a barn for several years. I have cleaned and rebuilt 1 of the carbs, and now it takes a while to get running. The headaches are that now when you hit the throttle the RPMs respond and it takes quite a while for the idle speed to return. I am waiting on a new spring for the slide, and have put a very fine coating of Vaseline on the side of the slide. It seems to slide easier(smoother). I will try again and then if it isn't working better I am going to get some better grade of Carb/Choke cleaner and try it again. I just want to say that I am impressed with the information that is/has been shared by others in this thread. Thank You, it WILL be used by others. The second carb has been removed and it is a mess, the choke plunger was stuck so hard in the carb, I had to break the cable to remove the carb. I was able to finally get the plunger out of the carb, new plunger, choke cable are on their way. Just want to tackle one at a time.

Welcome to the forum Steve, May I suggest this thread http://www.suzukiatvforums.com/forums/repair-maintenance/16881-carb-cleaning-my-way.html to help you clean the carbs. You may find some of the info helpful.

The same thing can be said for the fuel pump diaphragm and cause it to suck fuel through the vacuum line on it as well.
