Howdy,
I have a problem with my buck and I am out of ideas. The engine will not run correctly on its own, it will run on ether. Please see the image of what I have diagnosed the issue as. The atv is a John Deere Buck 500, a rebranded BRP Traxter. The engine will not run with the plug-in. I would also be willing to just let the thing go for $1000 if you are in the central Tx area

Need to pull the carb off and clean the main jet and any other removable tube that has holes in it.

 

If it runs on starting fluid or ether, then it's not pulling fuel up correctly from the main jet.

I went ahead and bought a new carb, they're cheap on Amazon.

Cheap doesn't mean good. Most of those aftermarket knock off carbs will be off right out of the box. Either too lean or too rich. Or even leak fuel.

 

Cleaning the stock carb would have been easier. Takes like 20 minutes on a bench. Maybe I'm just more mechanically inclined than you are, so that's my mindset.

I 100% agree with you on cheap parts, however the two options for carbs is $40 on Amazon or $700 OEM. I will try to clean the carb first though.

You check the fuel pump?

Getting great fuel, almost makes me wonder if it's getting too muck=h and that is what is causing gas to spew out of the carb

If the carb has a float/needle valve then it sounds like it's stuck open stuck open

She runs and hauls ass!

 

We bought the machine about 10 years ago at an estate sale. We then used it for about 3 or 4 years, then it sat in the shed for about 6 years. Nothing was broken, and it ran good, but we got our hands on the greatest thing since sliced bread, the Gator. In 2022, we decided we wanted all of our play toys to be operational, so it went to the dealer. Deere diagnosed a bad carb and refused to work on it after learning how hard it is to find parts for it. I found an Amazon carb and threw it on, it never quite ran right, and it got put on my back burner. Fast forward to this thread, I ended up putting another new Amazon carb on it. The only issue I have is keeping the fuel pump primed, I think a check valve will fix the issue.

      I suspect at some point in the near future, the hardware will be free and you pay a subscription to access the vehicle - alldata style.

      BAK MX4 EZ-Lift Install and Review

      By parthery · Posted

      I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.
