Ok, so I had no spark issues and foundy coil was bad. Bought a caltric coil, put it on and fired right up...for bout 20 minutes then it backfired once and again, no spark. I put it on my buddies 300 and it runs. Checked my cdi the same thing, but still no spark. Now I got my old coil and was ohming it and got reading of .01 on primary and 11.89 from POS to plug ( meter set on 20k ) new coil reads same primary but 12.83. what gives? It tests bad but runs my buddies 300, helllllllpppp

Everything every forum has spoken of I've bought sealed airbox completely tight unplugged black wire on trans. I have literally done everything in the book.Checked oil today full of gas anyone no anything what might b wrong. Next I'm taking head off and making sure valves seat any ideas.
I have an '02 Taurus with 85k miles on her that I just bought. Today when I was checking something under the hood I noticed this metal line cold and dripping with water...
I had the air on but turned to the position of arrows pointing out of the dash and floor vents only. The defrost or a/c function was not selected. It seems to be doing it consistently. I haven't traced all the parts of this car's a/c system yet but I don't know of anything else under a hood that turns cold and sweats. Why would my compressor be working when it's not selected? What tests should I run?

This is a good question asked by @Johnny Chancellor. I put it in a new topic so it does not get lost. We all know we need a cdi box but I bet a lot of the members here don’t know how it works. This is a good explanation of a cdi box including what it does, how it works and what “cdi” stands for.
Ive posted two links here. Feel free to add to the list!

What is a good option for a 13 year old that is dying to get her very own atv to ride? Thanks in advance for your recommendations. I currently own a Polaris Sportsman 570 and have been happy with the Polaris sportsman line but have ruled out other brands.

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.
A friend of mine has this Bayou 220 that started running bad and parked it a few years ago. I foolishly volunteered to take a look at it. I noticed right away the choke plunger on the carb was broken and probably the reason it was running bad but now the old gas was evaporated and like turpentine. Before i even tried to start it, i drained/ thoroughly washed the tank out, new fuel filter, new fuel lines. Blew air through the petcock etc. Changed the oil and filter and air filter and new choke plunger and cable. I disassembled the carb and rebuilt it with a kit. I cleaned the main jet with solvent and poked a wire through it to make sure it is clean.. the engine now fires right up with the choke on and dies when i take the choke off. I adjusted the air/fuel screw to about 1.5 turns out and the idle screw about 2.5 turns out. The rubber boot between the carb and head does not have any cracks in it so I don't think it is leaking air. I originally had the clip on the needle on the second from the top ring... when i moved it all the way to the bottom it starts, runs and idles really fast and will idle eeally high with the choke off but if i adjust the throttle cable and/or idle screw to a slower idle it will sometimes stall but the idle will go up and down every few seconds and when you give it gas there is a hesitation... i tried moving the clip down to rhe second from bottom and same problem... i replaced all the parts in the pic to the top right. However, there appears to be a small o ring, washer and spring left over from the kit... i did not see these get removed..... a) any idea if where these extra parts go and if i need them and b) any other ideas on why i cant get it to idle right or carb adjustment ideas?
So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
It will run and idle decent now but when I give it gas it dies.
Does anybody know what could be wrong?
I also changed the spark plug and air filter along with the oil and oil filter.
