WR400 won't idle w/o choke
Posted November 05, 2005 - 04:17 PM
I have a 2000 WR400 that I bought used about a yr ago. I rode it all last winter and stored it through the summer.
Now when I start it it'll start fine with the choke on but dies as soon as I turn the choke off. It'll run if I hold the gas on while I turn the choke off but dies as soon as I let off the choke. I tried turning the idle up but I have to turn it up so much to get it to idle that then I can't start it b/c the gas is always on.
I've tried adjusting the pilot screw... starting at 1 1/2 turns out and going in 1/2 turn increments out to 3 turns out. Didn't change anything. Also pulled the carb opened it up pulled the jets and sprayed it all out with carb cleaner... also didn't help.

i would suggest taking the carb off and bringing it to a good local shop for a "full carb clean". if it is a good shop/tech, they will:
-completely dissemble it
-soak the carb body in a hot tank
-blast out the body with brake clean then air
-soak all the removed parts in "carb clean"
-clean all parts with brake clean and then air
the process takes a few hours but just because of soaking time. it only takes about 20 min in hands time. shop should charge any where from .5h to 1h @ there shop rate.
also if it has been sitting for a while change the oil and drain the gass tank!
