Carb & Valve Specs for 1993 Suzuki QuadRunner 300

Hello everyone!  Just joined up.  As an introduction, I've had a Kawaski Bayou KLF300 2x4 since my Dad bought it new in '86 (nearly as old as I am), done a lot to keep it running through the years, especially with starter motor and carburetor work. 

I'm also working on a 1993 Suzuki QuadRunner 300 for a friend.  Seems original carb was MIA so he bought one online, put a 120 main jet in and then asked if I could help - still running bad.  So I'm here asking if anyone has the specs for idle screw turns, float height and valve adjustment specs.  Looking to download the service manual soon from here when I'm able to.  I've cleaned out the carb and reassembled it, it had some assembly errors, and so far got it to start and idle fairly well, bit unstable, and it drives good but tends to stumble when starting out with light throttle, and then when releasing the throttle sometimes it dies.  Think I'm getting close to having it dialed in.  Also have to look at the rear brakes, pedal goes through the floor and no braking at all.  Everything else appears pretty good, even the speedometer works.

Thanks in advance to everyone, cheers!~

Hi Bender, I got my friend's KingQuad all dialed in, brakes fixed, now starts and runs great, he's happy.  Could you give me some symptoms of your own, and I'll see what I can figure out.  I have found in the past that spark problems are very much on or off like a light switch - it either works or not.  Much more common is fuel problems.  Cheers!~  Bellarmine

Nice quad in the profile pic there Bellarmine.

I agree about the cdi, they rarely give problems.. the unit itself mostly go, or die. The fuel system gives more running problems. The charging is a common cause of bad running though too though.

      Another Bayou with no spark!!! Thrown so many new parts at it.....
      By Filthy_Mule777
      I'm currently pulling my hair out over a customers 98  bayou 2x4 KLF300b. I've changed every electrical component on it twice and in a couple instances three times. Still no spark, I am baffled. Initially customer brought it to me complaining of a hard start no start situation and in fact, it wouldn't start. I changed the starter relay, spark plug,  CDI box, and starter circuit relay after which it fired right up ran very well but then started having issues with the neutral switch/light where it wouldn't come on and wouldn't allow it start or even turn over. I found in the wiring harness a loose connection, I got it taken care of and secured and that solved the problem. So now that it would crank up again and run fine I called the customer over to test it out see what he thought as I've never heard it run before and I wanted to get his opinion on how it was running. Customer ride it around a little bit pulled it back on my carport and turned the key off and said it was great, and had never ran better or started so easily, then we set up a time for him to come pick it up the following day and he left. Well where he pulled it on my carport and shut it off was in the middle of the carport so I jumped back on it to park it off to the side,  crank it up no problems put it in reverse went about maybe 18 inches and it stalled and ever since that point it has not had spark or run. I replaced the CDI box again with a better brand, I replaced the ignition coil twice put another starter relay on it and I've also changed out the stater and the pick up coil (pick up coil twice) and I'm just I'm lost I don't know what else to do to it. I've had this customers  four wheeler for four months now whereas he's a patient guy I need to get it out of here so I can move on to something else. I've seen dozens of threads across  different sites for off-road, 4 wheelers, ATVs, UTV's, whatever and they are all experiencing the same sort of issue but they never ever post hear the problem was or  the fix. So I'm hoping somebody here has a little bit of knowledge on this particular issue sent since it seems to be so widespread.  Thanks in advance for any help or suggestions.

      KLF300 Bayou 1994 EU with weak or no spark issues
      By Params_sweden
      Hi, I have an EU '94 KLF300 Bayou with ignition issues. I got it last summer and used it for about 20 hours, then one sunny day we used it for about an hour, parked it, and then it didn't want to start again. It has a *really* weak spark, I've only been able to see it once while testing. 
      I'm just getting started on this, I'm going to go through all the weak/no spark trouble shootings from the manual. Since I've already invested like 10 hours digesting the manual and forum threads that I possibly can, I thought that it would be nice to create a thread like this in case I come up with a solution that can help someone else.
      So far I've replaced the spark plug, I will replace the spark plug cap with a NGK VD05F (5kOhm resistance). I'm going to check the resistance in the pickup coil, stator coil and ignition coil next. I have tried two CDIs, right now I mounted the original CDI which actually gave the most output to the spark plug out of the two
      A question for you, is it possible to make any assumptions about the CDI by measuring the resistance like in the manual? There's a "resistance table" that you can refer to when measuring between the different connections. I'm asking because I haven't yet seen anyone in the forums that has mentioned that they've measured the CDI resistances and made any conclusions from that.
      I'll attach a photo of my Bayou
      Pär, Sweden
