1998 Polaris Xplorer starts and quits

[pajeepguy]

We have a 1998 Polaris Xplorer 300. Havn't had it running for about a year. It cranks, has good spark but will not satart without starting fluid. 1 shot in the carb, full choke on and it starts and runs, on very high idle for about 45 seconds then quits. Another shot of ether and it starts again and again shuts down. I can't slow down the idle using the idle screw on the carb. and when I move the chock lever to middle or off, it still shuts down. Any ideas from the xperts?

the reason it runs on high idle then quits is because it is on straight ether. You r not getting fuel intothe carb. i would start with cleaning the fuel tank and lines and carb. also rebuild the diaphram pump and check your pet cock. if that is all ok then i would say that you have a vacumm leak causing your vacumm fuel pump not to work.

I agree with GEARHEAD, sounds like a carb issue, no fuel.

Well, I took the carb apart and found nothing visibly wrong with it. Didn't check the petcock. Not to sound like a complete doofus but where is the diaphram pump located excatly?

does it idle at all?

[GEARHEAD01]

it will be right under the fuel tank a part of the fuel control valve.

It does not idel at all. I will check the items you suggested and get back to you guys. Thanks for now.

I agree, drain the old fuel if it has been sitting for a long time. I still feel that carb needs a rebuild.
