1993 polaris indy lite 340 wont start.
Carbs taken apart and cleaned over and over and over and adjusted
Good compression
Good fuel
Good spark
Replaced end seal
pour a lil gas down spark plugs it will run all day long,. shit it off and it wont start again til you put gas down spark plugs.

Anyone have any ideas?
I have all the shops stumped. I really dont wanna have to take it in to a polaris dealer and get the high fees they charge...

I bought the sled from a older couple who has not riden it in 3 years, low miles.

Fuel pump isnt pushing enough gas to start? Check that out. When you cleaned carbs did you use a wire or something to clean out the pilot jet?

marv78g · 12-21-2012, 10:34 PM

New diaphram in fuel pump.
yes wire through every hole and used the good cleaning solution to dip carb in.

Have you checked pulse line?

marv78g · 12-21-2012, 10:40 PM

pulse line... U mean from the engine to pump. If so then yes has pulse from motor

I dont really know snowmobiles that well.... But spark plus gas should equal start right?

Like I said I have everyone confused on this thing. Im getting ready to part it out if I cant figure it out. Wanted my daughter to drive it but doesnt look like she will be able to this year. She is bummed... ANY ONE WHO HAS ANY INFO WILL GREATLY BE APPRECIATED.....

joshkidner · 12-21-2012, 10:42 PM

Pull it about 10 times and pull the plugs. Are they wet? What do you see?

marv78g · 12-21-2012, 10:43 PM

One plug is little wetter then other. But dont start.
If a lil gas is dribbled down cyl holes it will start.

joshkidner · 12-21-2012, 10:45 PM

Sync your carbs up. I hear this can cause issues.

marv78g · 12-21-2012, 10:47 PM

Ill try syncin the carbs again. Any other info from anyone would greatly be appreciated.
Thanks joshkidner. If you hear or can think of anything else please let me know.
Ill try to hop back on here when i sync them again n let ya know what the outcome is

joshkidner · 12-21-2012, 10:49 PM

Ok. Its weird that it keeps running when you drop fuel in and it keeps running but wont start alone.

marv78g · 12-21-2012, 10:56 PM

Yes correct thats what has everyone stumped.
Ya can drive it for hours stop it go pull start it right after ya shut it off and it wont start...

Makes a very frustrating event

joshkidner · 12-21-2012, 10:59 PM

Yes that would be frustrating. Its like its not getting enough umph to start. Could be an electrical issue? Not pumping fuel fast enough? Anyway id just replace the plugs because they are cheap. One more thing to rule out. After its warm how many times have you tried pulling it? Maybe when it shuts off its sucking fuel backwards for me reason and it needs to be sucked back in?

marv78g · 12-21-2012, 11:03 PM

Nothing really electrical on it besides coil n its getting spark.
Pull start only. Doesnt have electric start.
As far as plugs... Well lets just say I could buy stock in NGK by now.. LOL

Id say about 10 pulls, Get wore out after that... LOL

How about adding a primer to the carb or something like that?

You could add a primer. Alot of people dont like straight gas burning sithout oil until enough gas has been burned to pull in oil. I dont understand this at all. Try putting your mouth around the gas tank and seal it and blow in air. It should push gas through the lines all the way to the carbs just like a primer. See if it magically works!

aduck · 12-21-2012, 11:15 PM

Thats not how the primer works on a sled. Do you have air in the fuel lines when you shut it down? U could add a primer but carbs need the nipples for the lines to connect to

The primer would have to be on the line somewhere.... On my sled if i blow air in it goes all the way onto the carbs and practically primes it. Just seeing if it work. Hey maybe it will. Not much else to check

aduck · 12-21-2012, 11:23 PM

On a sled it t's of the fuel line and literally squirts fuel into the intake. Blowing in your tank is going to floods your bowls. If they take any at all. Point if the needle/seet

I have the same issue with my Bravo! I dribble a little gas down the plug hole for the first time of the day, but after that it will start again all day!

I have a primer for it and I believe that will fix it! Most all older Skidoo's have primers!

RXL · 12-22-2012, 06:44 AM

I think you still have a crank seal issue... Doesn't appear you have a strong enough signal to pull fuel through carbs.
Adding a primer may help the starting issues but lead to a melt down .
Try having someone pull it over while blocking the carb opening with the palm of your hand and see if it gets wet with fuel.

marv78g · 12-22-2012, 10:58 AM

I replaced one of the seals already.
When one puts hand over the carbs while another pulls engine over one plug is wetter then the other.

Is this something I should even fix? Or just part it out on ebay?

Just wanted something for my daughter to ride. I have $500 into it so far
