  1. Start by jumpering directly from the battery to the starter momentarily to see if it spins over. Give the starter a rap if it does not most likely the brushes in the starter are bad . If you have a meter check to see if when you press the start button voltage goes to the starter. Try rapping on the starter while holding the start button. If you have no power to the positive on the starter the problem could be in several places . Start at the battery . Does it show 12v or a bit more ?.. Next make sure battery terminals are clean and tight .. Check battery ground cable to make sure is has good contact to the frame check starter solenoid .. Do you have battery voltage to it ? Check output from the solenoid. If no voltage there the relay may be bad. Power on the output then check wire to the starter for a break somewhere .In all this I am assuming the click you hear is the starter solenoid pulling in . If there is no power to the solenoid the problem could be simply the quad is in gear and the safety switch stops power to the starter ..
  2. Happy Birthday to your wife .. She sounds like a keeper !
  3. I have friends in the 100 mile / Canim Lake area , but my daughter is in Kelowna. My sister , niece , nephew and their families are in the Shuswap around Sorrento. Stepson is in Kamloops and oldest granddaughter is in Pritchard. I'm looking at someplace close to Kelowna , out towards Vernon.. For all our American riders , this is all great open country with mainly rolling hills , much of it hot and desert dry in summer. Not a whole lot of snow in winter with moderate temperatures equivalent to USDA zones 5 and 6. Here on the coast the Fraser Valley is flat farm land with the surrounding mountains pretty densely forested and logging roads closer to goat trails. A lot of them are not much more than one narrow lane wide and in many places you don't want to go off the road .. Some slopes have nearly a 1,000 ft. vertical drop from the road to the valley below. Still lots of places to explore though. Riding is mostly unrestricted. ATVs need to be registered and carry liability insurance but most riding is unrestricted on where we can go. Not a lot of having to stick to designated trails in BC.
  4. Start to worry if she starts looking a singles vacation in exotic places My old 1991 Honda Fourtax 300FW goes fast enough for me. There's very few places we can really open them up here anyway , but lots of places we can get into lots of trouble . the winch on front has helped many times. I usually run tail end Charlie with friends that only have 2wd . They go ahead and when mired down I pull them back out LOL. I'm glad that at 76 I still bounce fairly well if I take a tumble. Would like to get a side by side so my dog can ride shotgun with me , but they're a bit too expensive . Maybe next year if I sell here for a good price, buy in the interior and have enough left over after the move .
  5. You'll have to trace out the wiring on it . There is a safety switch or relay not working in the ignition circuit. I would guess most likely a relay or possible broken wire since it turns over on the starter. Usually when safety switches fail the starter also will not spin. It is not getting power to run when the start relay is energized so start there after checking for an obvious broken wire.
  6. Mikuni is actually a Japanese company. China can produce some junk parts , but unfortunately so can Canada and the US. China is also capable of producing some very high quality products , and if you look closely you'll find an uncomfortably large number of "American" or "Canadian" products containing some Chinese made parts in their makeup. Dismissing any countries products as junk out of hand is foolishness in the extreme. As far as carburettors are concerned, unless it is corroded badly, very few actually need to be replaced.. They all can be cleaned but attention to detail is needed to get every passage and port / jet cleaned and unplugged . .Too often tiny holes in jet tubes and carb throats are missed. The only carbs I've ever seen that needed replaced were some on such things as weed eaters where the carb is plastic with some jets and parts non serviceable and plugged from being unused too long with old gas in them .
  7. Screw in to lean , out to enrich. Most carbs are set to 1 1/2 to 2 turns out from lightly seated. adjust in and out about a 1/4 turn at a time to find the sweet spot where it idles good ( usually just below max idle when warm) and doesn't stumble when you go to accelerate .
  8. I don't think rings are the problem. I've seen some pretty worn out motors start right up without a problem.. My guess is it is either running a little too lean or the choke isn't working. Cold motors need a richer fuel mixture to start. That's why most carbs have a choke, either manual or automatic, or a lever to enrichen the mixture and fuel injection motors have a start enrichening cycle for cold motors
  9. Glad you finally got it . I would never have blamed the CDI being wired wrong.. LOL. usually wire electronics wrong and they don't work period and often all the magic smoke leaks out
  10. If it is the winch relay just remove the two activation wires at the relay and see if there is still the loud click on connecting the battery.. Disconnecting the power to the relay doesn't stop the relay solenoid from firing since it is connected to ignition switch power.
  11. Yes, the only adjustment on most carbs is the idle air screw. It mainly allows proper idling and when set right stops the motor from stumbling when you go to accelerate . If you will be regularly running at those altitudes you would need help to re-jet your carb. If it is just for a short time , I wouldn't bother with the re-jetting. You'll lose some power (18-20%) but unless you're into full bore running you'll hardly notice it . The worst you might notice is idle and stumbling off idle and that can be remedied by the air screw adjustment and that setting is likely only to need about a 1/4 turn from where it is now. The idle air screw is likely to be the only thing on your carb to have a thumb screw for adjustment. It is normally only about 1 1/2 to 2 turns out from seated.
  12. You should be able to clean all the jets and passages in your carb. You should not need a new one unless that one is seriously corroded.. Stalling on giving it the gas is usually a lean burn problem caused by air bleed screw misadjustment or a plugged and overlooked jet or missed hole in one of the fuel tubes. There are some really tiny ones easy to miss. If there is an acceleration pump to give it a momentary shot of gas that could also be faulty. Those are all the fuel side. The other thing is ignition breakdown when combustion chamber pressures jump with the throttle moved off idle. Do you have a spark checker to see if the spark is still good when you hit the throttle ? If spark disappears when you do you know the problem is in the ignition circuit. If you don't see any hesitation in the spark give that carb another tear down and very close inspection. You need an exploded view of that carb to see where everything goes and look for overlooked screws , like some carbs have .. Some carbs have both an air bleed screw and an unnoticed fuel screw as was noted in another thread on another machine .If it runs at idle and stalls on acceleration it is fuel or spark. Fuel is the most common problem . I'm taking it for granted you have a new properly gapped plug and a new plug wire.
  13. Glad your transmission is ok. It's a lot cheaper changing out a differential from a wrecker. UI know the feeling. Years ago I thought my transmission or transfer case had gone on my 4x4 and it turned out to be the differential that time too. Mine started with a bang and crunch and then got progressively worse until I got it to the shop.. by the time I got it there there wasn't much left of the differential gears
  14. Power loss in carburetted engines is about 3% for each 1000 ft. of altitude. You would need to lean our you engine a little for those altitudes to keep it from running too rich.
  15. I added a pdf of the wiring of the various connectors used in vehicle socket and trailer plug wiring to the "Other ATV files" section in downloads.
