So not even a kick over for a sec. Even with a shot of start fluid. Or giving it some gas.

You can buy a curtis sparks tps bypass or make one your self. By taking the wires going from the harness to the throttle and cutting it on the throttle side with room to splice them together.

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      I have a 2000 Honda trx90 I got from a buddy for free he said it needed a carb so I put his old carb back on it to try to get something out of it and it does not have any Spark. I already replaced the ignition coil I don't know much about four wheelers but I am a technician so I do know my way around a motor any electrical help would be wonderful or specs I don't have the best digital multimeter either.

      Hi Guys, I'm a newbie but pretty handy with a DMM (controls technician). I have been fighting a junker quad i picked up as a project bike, was assured it would run if I replaced the battery and cleaned the carb. I replaced the battery, rebuilt the carb with a OEM kit. FIxed all my switches and foul played circuitry from the last guy.... So I could get it to start long enough to test the quad, it seems okay from a trans/engine point. However I couldn't get the carb adjusted to idle to save my life with the idle air screw or the thumb screw on the card for the slide. I took it to a friend who is much more familiar with yamaha and quads and he double checked my carb rebuild all was fine, he adjusted the float to make the fuel not overfill which i missed.
      He pulled the air intake, got it started and couldn't get it to idle with or without air filter. We started looking at the spark plug (new) and he tested it with a spark plug clamp meter, tested good, pulled it and grounded and it had spark but he felt it was weak. I order a working used oem coil to try the easy things first. When I ohm out the coil on the quad with my Fluke i'm seeing .4 ohms on primary (ground lug to male connector) and 18K ohms on secondary (inside boot to ground lug). Seems like this forum is full of bear trackers so I'm hoping someone has some ideas to help me figure where to go with this. His thought was he know I ave fuel and he knows I have air, spark would be next. I have spark but possibly weak. Thanks

      I know this tooic has been addressed by many, I’ve looked through many forums and pages. I did not find anything like the problem i have.
      I have a 2007 Kingquad 450. I have a new fully charged battery. When i turn the key, the dash flashes and seems to struggle before getting fully lite. We can hear a small relay near the computer clicking, i think it is the fuel pump relay. When i turn off the engine kill switch and press the starting button relays click and all the power shuts off, i turn the key off, engine kill switch then start over, power is there. Atv will start with pull start, but not elextricly. if i try to use my winch, all power cuts and engine dies. 
       
      Can anyone tell me what it may be? or has anyone fsced an issue like this before?

      I have a 1999 Sportsman  500, it was running fine, than started to lose power in the winter, I adjusted the idle screw and away I went, than a few weeks ago it died, I have found that i am flooding the engine, compression was at 70PSI and due to the compression release mech. i assume i am good as it compared to the same PSI on a 2000 sportsman 500 i have. i cannot start the atv unless i go full throttle and it starts an runs for about 30 sec than dies, again it is flooded. i ordered a new carb off ebay as i could get one for around $40. put that in same issue, i have checked the timing, (good), valves out of adjustment i adjusted to .006 still same issue, i have found the exhaust lobe and rocker arm to have some wear, i have ordered new ones, but am looking for any other input in this area as well. would the exhaust cam and rocker arm cause the engine to flood? i have used a bore scope and the piston liner has good cross hatching still? any input would be great.
