Need Arctic Cat help!

[muledeerarea33?]

Did ya try adjusting the carburetor? Idle, mixture screw may be off. When it's running mess with the adjustment. But first!!!! Make sure where you started from so you put it back if it doesn't help. Not sure if there's a vac port on the carb like a vehicle but if there is hook your mighty vac up and try to get as close to stoichiometric (14.7:1) but just a bit richer.

My Polaris does the same thing. Needs a carb rebuild kit. No amount of cleaning is going to fix it.

 

And my carbed Polaris has a fuel pump despite what some snot nosed little wanna be nascar mechanic tried to tell me once.

No offense but my Rhino is looking better all the time. Rebuild carb would be my suggestion

your arctic cat has a vacuum pump, and not a true fuel pump like an EFI uses. It helps pull fuel under vacuum,when the engine is running. Trace the fuel line from the petcock to the vacuum pump to find it. it could be plugged or bad. My Sportsman has a vacuum pump.

not necessarily.

 

If the tank is in the front there is no pump. Between 05 and 06 some arctic cat 500s have a tank in the front and some are in the back.

 

You keep asking questions without answering any.

 

I assume your tank in the front because the rear mounted tank has no petcock. That said if your not getting fuel "thru the carb" the plunger that is connected the the float is plugged.

Yes, front tank. No fuel or vacuum pump. Straight from petcock to carb. Will look at a carb rebuild kit. Thanks everyone. This has been a frustrating but good learning experience. Normally I would never touch such things but I have been feeling emboldened lately!

I checked the direction of the fuel filter also. That was one of those things to check while working on all the items listed. Thanks.

the info I looked up on your quad showed a vacuum pump for fuel, but looking further, that is only for a rear mounted fuel tank. yours is gravity feed.I just wonder why its not getting fuel?

[My Rights As An American]

Thanks for looking snapshot. I cannot figure out it either. It is clearly being starved of fuel but I cannot figure out how our why. I will play with it again in the next day or so after I do more research. Thanks for taking time out to look it up and help!

No problem. I don't know anything about Arctic Cats, but all quads run on similar engineering.

I also have two 2005 AC 500 quads. Mine are rear tank, vacuum pump. I had a problem with one of them last year, after leaving gas set too long. But it would idle fine, but cut out under power. I drained the tank and replaced the fuel/vacuum pump first, since it was easy to get to...under the seat. Didn't fix the problem. I rebuilt the carb and that fixed it. Most likely you will need to rebuild the carb. It is pretty simple. You can get the kit from Bass Pro.

Several years ago I downloaded the service manual, and that is a big help. I googled it and found it on a small engine/lawnmower repair shop website...if I recall correctly. I would post it, but the whole thing is over 250Mbs.

Here is the link to the manual:

There is a "start here" section. That is the table of contents. You can click on a section and it will open it, instead of scrolling the entire manual.
