Suzuki 2003 lt 160 firing problem

[cgeorgerun]

I have been rebuilding this ATV for about a week and a half now. I rebuilt the carb, changed the air filter, and cleaned out just about everything I could think to clean. I tried starting it last night and the starter button would not work, so I pulled out the start button and saw that the wires were useless. I finally got to a point where I was able to hot wire it and get the engine to turn. The engine turns, but will not fire. It is clearly a problem with not getting spark or not getting fuel. I just replaced the spark plug and battery. At this point, I am a little stuck as to what approach to take. Im thinking I need to put starter fluid in to see if I can get it to turn over with that and if it does, I need to work on the fuel system.

Has anyone worked on this quad before who has any experience or advice to share? I am an engineering student at Clemson and this is a summer project for me to rebuild an ATV instead of buying a new one. I am ready to learn! Thanks!

If the plug is wet, its getting fuel.

Even if its not getting fuel, not having a spark is the main problem.

You grounded the spark plug and turned the motor over, and there is no spark, correct?

If correct, check the on/off switch and any others. It may have a brake switch. If all that stuff is good, you need to test the coil and stator (generator). You will use a ohm meter. You will need to find out the correct readings.

That will keep you busy.
