1994 Polaris 400 4x4

Hi,

I just bought my first 4wheeler. I have a couple questions.

1. What are the stock carb settings?

2. Are these things known to make a bunch of racket at low idle? The engine runs at low idle, but it sounds terrible with all sorts of rattleing and knocking. Once I open the thottle it smooths out and sounds fine. Could this be the transmission? If I set the idle any higher, it won't shift into drive without the gears grinding.

3. What is the override switch on the left handlebar for? I was told you need to use it when you shift into reverse, but it seems to shift into reverse the same whether I depress the switch or not.

Thanks for any help,

Jay

the override switch will make it go faster in reverse. put it in reverse , then push the button then your gas.

the stock carb settings for a 94 polaris are

Main jet...200

pilot jet...30

air screw setting 1.5 turns out

jet needle and clip position...6dh29-3

needle jet..0-6(480)

As for knocking and pinging problem i have the same problem with mine. i dont know if it is normal or not

1994 2stroke 400 is 1.5 turns out on the air mixture screw, main jet size is 200 and pilot jet size is 30, also with the overide switch it will engage 4 wheel drive in reverse.

Thanks all. Maybe I'll post a Youtube video of the low rpm racket it makes.

o now i did not know that engages 4x4 in reverse...when u put it in 4x4 is their a anything u have to do for it to engage or can u just press the button, i just picked up a project 94' polaris 400 and dont know anything about the 4x4 or how it works.. i replaced the indicator light bulb that goes inside the switch and it does not turn on. does the atv have to be running or in motion for the light to be on?

Do that and post the video in this thread. The noise could be norma,l two strokes have a thrashy sounding idle by nature, if it is worse than normal, it could be an indication of worn crank main bearings, rod bearing or wrist-pin bearing.

the noise at idle i would have to say is the clutch against the cover. im not sure about the light. and i have the same problem with my carb a cant get it adjusted right and its all clean
