Original problem - gas pouring out vent tubes - fix - new float needle and seat
New problem (maybe) - while breaking down carb and cleaning in there and replacing the above. One of the things I removed (foolishly) was item #'s 17,18,19 & 20 from the IPB located at this link CARBURETOR - 2005 Bombardier DS 650/DS 650 X

My question - defiantly appears to be an adjustable part - how many turns is required? I pray the answer its not adjustable based on how it runs and you would need to test run the quad after reassembling - then have to get back into the carb to readjust based on those findings.

ps. my ds manual is next on the list

Thanks,

Bill

 

thats the air-fuel screw, not sure on your ds , but usuall2-2.5 turns out is about right

 

With the bike warm and at idle adjust this screw out until the motor stumbles then back in until it smooths out. Like stated above you should be somewhere between 2 and 2 1/2 turns out from the bottom. You will be able to achieve stuble turning in and out so right in between the two is where you want it.
After you find that sweet spot adjust your idle speed and your good.

 

Thanks for the effort - but this screw is internal to the carb - no adjusting anything while its running

 

the parts you put in the post are idle mixture parts, an i have never seen them inside the carb looking at the bottom of the carb in front of the bowls there should be a place for them, on most carbs i have worked it like a tube that they screw into
