  1. Bogging is more often a lean problem than rich.. As Frank said , I'd pull the carb once more and look for any tiny, and I mean tiny holes in the tubes to the jets . They can be missed very easily because they're so small and not a brass jet as the bigger ones are . I don't know if your carb has the holes I'm talking about but many do.. Carbs and fuel mixture settings are often accompanied by a lot of my verbal lubrication here. Sometimes I wish I was multi-lingual so I'd have access to a broader range of "lubricant " phrases. They're so handy when fiddling with the small stuff and much better to use them than start tossing tools LOL
  2. I have done next to zero work on ATVs myself other than maintaining my own and helping friends with minor repairs and welding. I have messed with old school cars which are very comparable to non-electronic controlled ATVs. A carb is a carb whether it is on as car , ATV or any other machine .. They may be built and look different but they all mix fuel and air to run. The trick is finding all the quirks in how each is jetted and adjusted .. That's where manuals and advice from owners of similar machines come in. As far as the electrical end of it comes , I'm comfortable with points and coils, but have to rely on advice from others and, again, manuals when dealing with CDI boxes and electronics on newer ATVs. I know my way around multimeters and basic electricity. Got my HAM ticket back in the '70s so learned a lot of electrical theory to do that . I'm a retired Millwright and have tinkered with cars since my first one over 60 years ago, so I do know the frustration of working in tight spaces at times fixing things that engineers designed to be easy to build but hell to maintain. Most of the time when someone has a problem I might be able to help with, Frank beats me to it and gives very good advice . I can only add a little to some of it some of the time . I spend entirely too much time on my computer so I do know my way around searching for answers to all sorts of things. The flexible screwdrivers offered today are a lot more refined than back in the day I bought one.. Old ones were simply a flat head with a cable like shaft and handle. I never saw any with a Philips or any Robertson head. Now they generally all have heads where you can use any of the various inserts. Good luck on getting that carb tuned .. Takes a bit of time and patience ..... and far too often a lot of ummmmm " Verbal lubrication" to get the job done.
  3. You can get flexible screwdrivers . Walmart carries several different takes on them according to the hit on this search. https://www.walmart.com/c/kp/flexible-screwdrivers
  4. Look in the forum downloads section. There is the service manual for the '88 - '94 Honda 300's there
  5. I haven't found a free download of the manual for the newer ones ,but there's several pay ones available .
  6. I can't tell you how they're locked , but if it might be with thread locker , like Loctite , you could try heating them up good and hot with a soldering iron. Empty the tank , leave the cap off and no open flames to heat the nuts with.. Heat on them will kill any locking compound if present and will likely help to loosen the nuts if they are mechanically locked with a star washer or other means.
  7. Most likely it is the same switch located in the same place as in earlier models. There are Big Bear 400 manuals in the download section .. Check them out for the placement of your switch .. It may be something as simple as a bad ground .
  8. Yes that valve is easily replaced. Your local quad dealer may have one in stock or a quick search online should give you several sources and prices .
  9. Black Friday is also much quieter here now than it used to be. Online shopping has definitely taken a big bite out of the crowds and mayhem that used to be Black Friday. I'm sure the brick and mortar stores are hurting from the change .
  10. Sounds like you got hit by one of the exploits that compromise your browsing .. I highly recommend Malwarebytes to remove the ad installer and any other malware. The download is a free trial of the full version of MB.. When the trial expires you have the choice of paying for the full version or drop down to the free version. The free version does everything the full one does except it does not offer full time real time protection.. You must manually run it if you suspect some nasty has snuck in. I have used the free version for years. It automatically checks for updates when you manually run it. you can download it here: https://www.malwarebytes.com/mwb-download/
  11. Have a very Happy and Safe Thanksgiving to all my neighbours south of the line .
  12. A lot of "what ifs" to go with electric trucks and quads, especially if you're 200 miles in the bush. " Quad charges off the truck".... Great .. But how do you charge the truck if you're out on an extended stay ? Can both be reasonably charged using a small to medium 110 - 220v light plant of about 2 -3,000w ? To me , that quad is an ugly no go. 2wd and chain driven at that doesn't cut it in my book. Nope on the design on that "truck" too. I can see an electric 4x4 truck, but I would also like to see one with a built in gas powered genset to be able to recharge the batteries when way out in the boonies. It wouldn't need to be a fast charge , just one that could recharge it over a day with ability to restore at least 100 miles of its capacity in that time .
  13. Most likely nearly all, if not all of those starter "brands" are actually built by one manufacturer and just sold under the company names. You'd be amazed if you found out how many Ford , GM and Chrysler are shared with one another and Japanese or Korean makes; especially in accessory parts like starters , alternators and other electronics . Many driveline parts are also shared. I'd go with the least expensive starter offered.
  14. Since you found corrosion on the one terminal, check all the others to the starter. Try jumping directly from the battery to the starter terminal. If it spins over you know it is a bad connection or broken wire . If it does not the problem is most likely in the brushes in the starter. Press the start button and rap on the starter . That will often make the brushes contact and spin the starter over .. It may continue to work for a while after that , but if not it isn't very difficult to replace the brushes.
  15. 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 ..
