Very good, complete operation works for me so I get the entire picture at one setting, thanks for a super job..

Thank you!

Sir, I've spent 21 years in engineering & Internal Combustion Engine ( ICE shop ) I like to watch these type vids for S&G , but I just want to thank you for your video - Finally a very well made and informative video!!! My hat off to you 👍🏻

[@ProjectTimeGarage]

Wow, thank you!

[@stevegiroux239]

I like your detail explanation how carb works

[@ProjectTimeGarage]

Thank you!

[@BritishAirwaysCaptin]

3 years later but do you remember what you settled on with the fuel adjustment screw? Did you stick to 2 1/2 turns? Thanks for the videos. You’re the only guy I’ve been able to find who actually shows their work on these smaller carbs

[@ProjectTimeGarage]

I'm a little closer to 3 turns.

[@stevegiroux239]

Hello I got my quad running great I had the same problem as you did but I bought a new aftermarket carburetor for my awd 325 Polaris Magnum it wasn’t running right every time I throttled it it died then I remembered that the air filter cover had to be on just so the quad had its proper air supply and it runs great thank you for your detailed video 😊

[@ProjectTimeGarage]

Glad to help!

[@demon_or_angel]

Take a 12mm open end wrench and a grinder. Grind down the edges onnthe open end side. Then you have a wrench to take off the choke nut.

[@stevehernandez6642]

Great video. Thanks for all the detail. I learned a lot about how the carb on my quad works.

Glad it helped

great video! Def. Needed this after my polairs 325 starting issues, currently working on it now thanks to you!

Good luck, hope you get it going!!

@@ProjectTimeGarage question for you sir, you don’t happen to have the fuel line diagram do you? I know the pulse line goes to the right side of the carb. However I’m having issues finding which line goes where from the “fuel pump” to the Petcock to the tank. From what I’m reading the gas and reserve line coming from the gas tank both run to the petcock, on the left and right side hook up line. I’m assuming the middle line comes from the fuel pump. Long story short there is several misleading references online and I’d like your advice.

Thanks for this video, turns out the diaphragm that controls the needle has a huge hole in it so that's what my problem ended up being. I had a feeling that was the case, but I didn't want to believe it lol, guess its time to revisit evil bay, then I'm saying goodbye to this thing cause I've worked on it more than I've ever rode it.

Hi I’m having problems with my carburetor it idles as soon as I hit the throttle it dies and what could be the problem because I had bought a new carburetor and fuel pump and sometimes it will start right and I can throttle it but then it will die backfire I don’t have a tuning screwdriver for the fuel mixture what can I do I’m tired of taking it apart I must have taken it apart about seven times due to the carburetor issue

[@ProjectTimeGarage]

Most likely it's a fuel starvation issue. If it idles fine, but backfires and dies when you give it throttle, then the pumper diaphram isn't working correctly.

[@jasonmichaud7425]

Fun to watch though

[@ProjectTimeGarage]

Thanks!!

[@007Lynyrd]

I have this problem with my sons 325, turns over but wont start.....tried new plug and battery.....have to take the whole thing apart to see if its maybe the carb....frustrating

[@ProjectTimeGarage]

Basic rule of thumb - if you can squirt gas down the carb, it should at least sputter - even if the carb is junk. If it doesn't, then you want to check for spark, then compression.

[@im-that-guy-pal]

Next video.. how to replace burnt starter motor.

[@ProjectTimeGarage]

At least starters are cheap, fast and easy to diagnose. A good trade-off, in my opinion.

[@aidenmurphy2997]

Sir can you please try to tell me what is going on with my 1999 magnum 325 any help would be greatly appreciated? My machine will only crank and hit off with half throttle applied before starting the four wheeler it will not crank and hit off without throttle what could be the problem?

[@ProjectTimeGarage]

Sounds like it's starving for fuel. Maybe try a thorough carb clean.

[@aidenmurphy2997]

@@ProjectTimeGarage yeah man it could be a possibility but I asked my grandpa what he thought it could be and he said there’s nothing wrong with it I told him maybe a dirty air filter could be the issue but I’ve been checking it myself and it wasn’t dirty cause it only cranks and hits off with half throttle applied so wouldn’t it be starving for air? Cause when you apply throttle to the fourwheeler the butterfly opens which is letting air in and at that point it hits off and it runs like a sowing Machine(and google isn’t helping me with this at all(figuring out what it is or could be so that ain’t good)

[@davidpeech8738]

So what was the problem with the 325 . i have the same thing going on with my bike . Was told might be the CDI box

[@ProjectTimeGarage]

I finally got it figured out. There is a second video that goes through what all I found and fixed. It ended up being a couple of things. 1) a cracked intake boot on the head side and 2) they don't run well without the airbox lid on and sealed tight. Evidently those carbs are really picky about exact airflow, too much or too little makes it lean out big time. Check out the second an final video for all the details. Thanks for watching David!!

[@benniegoodman2645]

Awesome video how do I get to the next video solving the fuel issue

[@stevegiroux]

My Polaris magnum 325 is sluggish what can I do to have it run smooth because as I want to move forward or backwards it dies as soon as I give it throttle?

[@ProjectTimeGarage]

Most likely fuel/caburetor related, but one thing to check is the throttle safety kill switch. It's basically a micro-switch that kills power to the ignition if a "stuck throttle" condition is detected. Google has a lot of info about it and how to test it. May want to start there.

[@stevegiroux]

PTG this will be my first time doing this so wish me luck. Or should I leave it to the professionals?

[@ProjectTimeGarage]

@@stevegiroux If you're fairly mechanically inclined, give it a go. Take lots of pictures as you disassemble, it helps you remember where things go.

[@stevegiroux]

@@ProjectTimeGarage okay I will do that since I work on lawnmowers and weed whackers. Thank you

[@ProjectTimeGarage]

@@stevegiroux Yeah, this should be no problem for you then.

[@James-sir]

Heat gun for air filter removal on boot

[@ProjectTimeGarage]

Yep, that's exactly what I should have done.

[@jasonmichaud7425]

Hey you should have watched a video yourself man cuz you only had to take out their her box to get to the carburetor I have the same four-wheeler

[@ProjectTimeGarage]

I actually did, lol, this carb is completely under the tank. The tank has a relief molded in the bottom of it for the carb. I also have a 425 Magnum and an older 325, both of those can be done without removing the tank. Hell, I went as far as cracking open the old factory service manual (sacrilege, I know). It's procedure is to pull the tank, ugh! Anyway, not much way of checking valve clearances without pulling the tank anyway, so it had to be done.

[@stevegiroux]

Hi, I am wondering if I can change the middle part to have a speedometer cluster kind?

[@ProjectTimeGarage]

Not sure. There would have to be a speedometer drive somewhere on the trans or front wheels. Never seen it done.

[@stevegiroux]

Okay thank you for letting me know.

[@bobbyalitz6606]

1 thing i do not understand is why do you call a atv a bike i dont get it

[@ProjectTimeGarage]

No idea.

[@garywoody5594]

And this is why I'll never buy a Polaris and the fact it's belt driven CVT

[@ProjectTimeGarage]

I don't know. I think anyone who runs across any four wheeler as cheap as I got this one would have bought it without thinking. I'm not a huge Polaris fan, but I'd buy a hundred of them if they were this cheap.
