http://utvpartsandaccessories.com/intimidator/ This could be the place to look for parts. I think with the regulator, make Sure The prongs are The same as the plug. more than likely the parts are generic made by Wee Fewl Yu in China. Even though it says made in USA with American steel. Alot of other brands make them in the USA, but parts come from abroad.

Welcome to the forum, Mike!

If you could post a video of it running then dying, that would be great. One thing I would try is take off the air filter, and get either starting fluid or carburetor cleaner, and when it starts to die, spray it into the carb . If revs it back up, it can be narrowed down to a fuel issue. If not it could be a spark issue. Or a valve problem. Which is least likely.

Do you use OEM (Original Equipment Manufacture) or Aftermarket for Fluids and filters? feel free to reply which brands you use.

Yep, for the 550, a OEM mikuni is $170+ $60 seemed to be reasonable. I saw some for $30, or less but I really question the quality at that point. Interesting thing I noticed, I'm used to Briggs carbs made by Nikki or Walbro. This Mikuni uses a metal needle with a rubber tip instead of a metal needle and rubber seat.

Be sure to monitor it CLOSELY. Im sure you know, but gas will dilute the oil, and next thing ya know, (rattle rattle rattle BANG!) :D

I finally decided to take the carburetor off the mule and clean it, Pull it off, piece of cake.... Take off the bowl, here is what it looked like. Then I proceed to pull out the float pin, sigh As you can see, part of the hinge casting broke off. I contemplated JB welding it, but decided not too.Mikuni and Kawasaki are $170-$200 too proud of this carb. I stooped low and bought a $60 off of amazon. Is rather go oem but couldn't in this case. Oh well, nearly 20 years on 1 carb. not bad i guess. never took apart and cleaned, just b12 chemtool in the tank every so often.

does it stay running if you rev it up. I would start it and keep a constant high RPM. Did you put new fresh gasoline in it? I remember one time I got water in the gas in my mule, and it idled like crap and then die, but if I revved it up it would stay running.....

Okay, my 550 is a 2001. It has teeth all the way through the drum.

Wait, are you saying there at barely any teeth in your drum?

Happy Thanksgiving to you and your's Alex. Thankful for the UTV Board 👍 Gobble gobble

WOW!

Does it smell like gas? And you said with out filter, so you don't fill the filter, correct? Or do you just leave the filter?

If they changed the design most likely they would have changed the part number too, I didn't see any surpercession in the parts list.

Here's an old pic, that piece of metal below the cylinder, stick a flat head screwdriver in where it meets the other piece, it will have grooves cut in it, Stick your flathead in their and push the handle to the left, that will pull the Brakes in and give more clearance

Teeth in the drum look good? Are your brake pads interfering with it? To the bottom left of the wheel cylinder, is a little metal tab with grooves cut in it,get a flat head screw driver and pry that in and it should give your brake pads extra clearance.

I would check tightness of battery cables, and any ground wires. And clean them if corroded

Look up Pacific Eagle UTV. They make enclosures for almost all UT V brands

I was thinking of using one of my old head lights as a bed light for The mule, if we're loading fire wood in the dark etc we can see. There is a open electrical accessory connector I can plug to and run the wires alongside the roll cage, and mount a separate switch, I can just cut the old connectors and crimp on new ones, but does anyone know the name of the type connector this uses, all I can find are the square crimp connectors.

👍 Just an example I though of. Think of a. red gas can, if you block the air vent, it will only pour so much, when you unblock it, it breathes in..

Okay, I found the gas cap your mule uses, and it's like mine. I'd recommend replacing it. IF it's the problem

Generally you either replace it or I've let them soak in a solvent bath, ( gasoline) Due to EPA regs the cap vent is fairly complicated. Let me see if I can find a picture of The gas cap and see....

Oh yes, the gas cap should vent! try running it with the cap unscrewed...

Will it stay running if you rev it up to a constant high RPM? I would also play with the choke a bit, and see if it idles or won't die on partial or almost full choke. Did you replace the carburetor with a new OEM Kawasaki or a Chinesium off of ebay/Amazon? It's possible (Even on a new Low quality carb) for the float (which regulates fuel flow into the carb bowl) to get stuck in the closed position, which prevents any more fuel from flowing into the bowl. It's possible it's a vacuum problem. It's also possible, but not as likely the ignition coil is failing, but they generally don't start right back up.
