Can you please do a 2009 Polaris IQ Shift 600 double carburetor (It's like 2 carburetor's that are attached to each other side by side, not sure what the actual name is) I'm havin trouble with idle since I rolled it. Maybe float bowl? I want to understand that carburetor like you showed this video's carb :)
@christhelonewolf7464 жыл бұрын
Theres a hose coming out the bottom of the bowl. How is it suppose to fill up and trigger the float valve if theres a open drain at the bottom of the bowl? Mine keeps dumping all the fuel out the bottom
@DIGIT94 жыл бұрын
hose out the bottom is to catch water , should be blocked off with a bleeder valve or plug

I have a 2011 Arctic cat 570 it was running like shit flooding but it was still running and then all of a sudden it doesn’t run after I did a carb clean and I put it back right do you have any ideas?

The only Snowmobile I had problems with the carburetors was a Kawasaki Invader 440 that had power jet carburetors on it and the owner let to much water get in the float bowls and it froze cracking the bowls and no one had parts for them so I had to talk the owner into buying new carburetors for it

Thanks for the videos! Just cleaned my carbs on my 99 Polaris Indy 500. Replacing pistons and gaskets this weekend, due to compression only at 60psi. Hoping this is the resolution. Any advice would be greatly appreciated. Thanks again for all the videos and keep it up Digit9!

Great info. Been working on a 99 zr500. Had crap gas in it. Got it all back together and ran well for a week or so, and started having issues. #1.. going through a ton of gas, 3/4 tank in 62miles. #2.. running around 6000rpm sounds boggy (too much gas) but pin it, and it runs like a champ. #3.. been fouling plugs.. Advice?

low compression , clutching , or bad gas ?

Turn idle screw out so slide falls , or turn air screw in ? Or check placement of needle , or check throttle cable or check crank seal ? Pretty hard to tell with limited info !

@darcy321714 жыл бұрын
Regularly, the air/fuel starts at 1 turn from lightly seated. The Idle screw is usually 3.5 turns from lightly seated. This is just a starting point to get the machine to a running state. Then fine tune from there. There really i no magic number to be spot on. Hope this helps. Awesome video Digit9!!! Thumbs up.
