  1. The tools you have are fine. If you get into deeper work like CV joints and crank case separation, the manual will tell you. RTFM right. Or ask me. I might have a work around. Ive been to the bottom of 2 of these.

    My blog details the valve adjustment. I think I posted something else there about timing chain. Join that site. Hunting and fishing stuff you might be interested in.

    And semper fi. Thank you for your service.

  2. I did a similar job on a 93 a few years back. Detailed here: Suzuki King Quad project - Forums - 907Outdoors

    Sounds like the rig was pretty beat up. Do a valve adjustment first per the routine mx section in your manual. Next rebuild the carb and make sure its getting fuel. That its back filling into the carb could mean the timing chain has jumped. To check you have to remove the head cover.

    i get most of my parts off used from Ebay. Mufflers are hard to find cheap. Try local salvage yards.

    Good rig for a kid to learn on. All the mechanical controls and poor breaking system teaches them to operate the machine rather than just hanging on.

  3. The valve faces wear as they bang up against the head seats. This creates a gap on the sealing face that intake and exhaust gases can pass through. Hence on the compression stroke, it leaks. Cars have hydraulic lifters that compensate for this. Wheelers don't. You have to back off the rocker arm stems to facilitate full valve travel. My kids ride these old king quads about 400 miles a season and I have to adjust valves every year.

    Not hard to do, just a bit intricate. Get a manual and read up on it.

  4. I wouldnt go for a new carb yet. You have the original carb right?

    My first thought is valves. You said they were checked. Was it done at TDC and did you have slight play in both the push stems? Gap should be around .005 inch.

    How is your spark?

    How is the compression?

    Back firing suggests a rich fuel mixture. Check that the choke is not stuck open and the fuel delivery system vacuum tubes in the picture. Should be no fuel in them.

  5. Excellent. I had a tank venting problem on an old LT230. Would run for a bit then just sputter. After a while start back up again. Rebuilt the carb, changed the pet cock and in general banged my head on it. Vent wasnt big enough on the tank cap. Good idea on the needle jet adjustment too. I still recommend a valve adjustment if its never been done.
