Bought the girlfriends son a 2004 lt80 that was really clean but didnt run quite right. It had been setting so figured a good carb clean would help. It cranked and ran down the road like a bat outa hell. Slowed down to turn and it died. Full throttle and alot of cranking it fired up. Run like a bat outa hell then die on decel. Brought it home and oulled carb and cleaned it good. Primed carb and took off. Ran great.....decel it died. Now the only way it will crank is with choke and it fires right up. Click choke off it dies. Turn choke on fires right up. All stock everything on this. How man turns out on idle screw? Thanks for the help in advance!!!

 

Welcome to the forums.
I suspect a carb problem. You can try boiling it. That's helped some ppl.
If that don't work, we should check the compression and make sure the pipe isn't plugged.
There is no exact idle screw setting.

 

Thanks LT80. I cleaned the carb pretty good. Left the little black boot out of the bowl on accident but from what ive read of your posts its not needed. Is a carb "kit" something I need when I pull it back apart? How do I check to see if pipe is plugged up?

 

When it does fire up, see how much exhaust (pressure wise) is comming out of the pipe. Removing the bolt in the bottom of the pipe may help.
If you think it may be plugged, You can try using a propane torch and heating up the bottom of the expansion chamber or remove the pipe and put it in a fire/charcoal/etc till red hot and blow it out with compressed air Spam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word careful!

I don't think you need a carb kit.
Check the pipe first is what I'm thinking.
