I have been working on a 2004 arctic cat 400 that will run for a while with a new coil installed then after a few min start sputtering and quit. Checking the coil afterward it it is burned up. There is 350 Plus volts going to the coil and I'm not sure if I need a CDI or its something else? Flywheel magnets have been ruled out!

I am goin nuts here! I have a 04 400 air cooled 4x4 , I'm a atv,car,truck,mower mechanic for yrs,just sayin. Ok it cranks and kinda fires now and again then after 5 min of cranking and stopping itl start if u touch throttle itl did then u start all over! If u let it warm up sumtimes u can throttle it up other times it just does! Just depends on it? When it stays running it runs awesome,no problems except it just does randomly like u shut key off? Sumtimes itl start right back up others itl do the no start thing! IV put new plug,adjusted valves and hot tanked carb? I'm at a loss here guys! Please any other ideas? I don't think it's anything to do with flywheel? It's not the auto it has a hi low reverse lever on left fender and foot shifter? Help please lol

i know this isnt an atv but same type of thing. I have a riding mower im fixing and selling for my aunt and it has a dead battery. i jumped it off my atv and when i turn the key nothing at all happens. i tried jumping the relay still nothing. this is with the seat down. you wouldnt think this mower would have issues as its a top-of-the-line brand and almost brand new (aunt found it for a good price, still got tits on tires, just sat for a couple months in a mechanic shop

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.

Was using the quad the other day to shuttle wood from my pickup to my wood pile. When the job was done I turned off the Quad and heard a bit of a racket from the front end. When I got down underneath the sound seemed to be coming from the fan housing. fan was moving in spurts and not quickly... much like a computer case fan that's had it's day. What I know.
Temp sensor is ok, as the fan tries to activate fan is getting some voltage as it is attempting to spin. When I first bought it used I tested the fan direct to battery and it was fine. The fan was working ok even not direct wired as I went on a couple of rides and when stopped and idling the fan did run Seems to be free spinning with my finger read up in the manual and they require me to drop the rad. now I'm not opposed to that as the rad has some damaged areas I want to try and straighten out. But if I can get the fan working without, I can leave the rad as it is until next year.
Fan assembly is about 300 bills, any work arounds or alternatives? I even thought large computer case brushless fan. smaller ones are about $7 larger ones better quality probably far below the 300. They run standard 12v DC.
Anything I should be doing before dropping the rad... other than check for obstructions even though it seems to spin, and trying to hardwire it to the battery again for a test to see if it acts the same?

Hi Everyone
This is my first post and I was wondering if there is anyone who can help me solve a problem I have with my Yamaha Kodiak 400 4x4 Fitted with a Mikuni Carburetor . The year of the quad is around 1998, the reason I am not sure of the date is, there wasn't any paperwork and no details on the frame either.
The quad had a bad leak from the carb overflow which indicated that the float needle valve was blocked or passing so I replaced this and put everything back together. The quad ran really well until I took it onto some rough ground to have a ride around, a few hours later the engine started to run really rough as if the engine was flooding. I have removed the carb again and cleaned the needle valve out and the whole of the carb just in case there where any dirt behind it. Engine now runs fine again but fuel has started to run out the carb overflow again.
I have tried everything to try and stop the fuel leaking out the overflow but its still happening. My last thoughts where to adjust the float level and its still happening.
Has anyone got any thoughts on the problem or could suggest whats causing the fuel leaking out the overflow.
Thanks for reading
Kevin
