So if my carb is gettn to much air and not enough fuel ...can i adjust it by taking the diaphragm cover off and raise or lower the jet needle?

It depends at what stage you are starving for gas. The needle affects mid range. You should do a plug chop at 1/4 1/2 and 3/4 throttle.

yes about 1/3 throttle it seems like its starving for gas...i just bought the new carb...i do see a adjustment screw on the bottom side of the carb...it would be hard to adjust if that has anything to do with the air and gas....but was told under the top cover there is a needle valve that can be adjusted...right now i have the breather intake hole closed off a little just so it would run someway decent but i shouldnt have to do that..ideals fine though

Disregard, I merged your 2 carb threads into this one, since they are the same topic. :wink:

      Hi, I'm new to ATV/UTV's and am looking for any advice that would help to repair my 2018 Ranger 500.  I got it from an insurance auction and have never owned one before.
      It looks like it was sunk deep.  Found rocks and sand in the roof, milky oil in the air filter box, water in the fuse box, etc.
      So far, I've cleaned the air box out, vacuumed most of the rocks and sand, checked the engine, trans and diff casings for cracks/leaks.
      The battery would not charge while connected so I know there is some short somewhere...probably the wet fuse box.
       
      I plan on drying out the fuse box and all connectors with a hairdryer tomorrow, check the fuses, remove/dry out the ECM and disassemble/clean the air intake.  Then install the battery and see if i can get it to key on and see what kind of lights I get.
      Need to know what to expect with the engine/trans...
      Thanks.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      I picked up a 1997 Yamaha Big Bear 350 2X4 a week or so back in non running condition, apparently they said it needed a new carburetor or a battery, I cleaned the carburetor thoroughly and got it running on idle and without choke now and it shifts into all the gears even into reverse. Aside from making me bounce a little when trying to start out with a bit of throttle the shock suffice to say needs work. Anyways I made a video of it running and would like your opinions on it, as to how it sounds while running. It seems like it has a little whine I'm not sure why that is maybe someone can tell me what it is. Anyways here is the video.

      My ATV has stopped charging the battery.  I have to charge it with a trickle charger everytime before I use it.  What do I need to replace to get it to charge the battery again?
      Thanks,
        Dave

      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
