Will not idle - Is the hot-start the issue?

[aztsail]

My '03 WR250F fires up just fine, but simply will not idle. If I give it a little throttle and the release it, the exhaust pops badly which would seem to mean that it's very lean and then dies. Never had this issue before. I have had the carb off, cleaned out the jets and also replaced the hot start plastic cover with a zip-ty metal one since the old pastic one was stripped. The zip-ty fuel screw seems to have all of the important parts, o-ring, metal ring, spring so I'm a little lost at this point. Could it be that the hot-start is not seating properly? I can take another look at the pilot jet and make sure it's clean. Any other thoughts that might help...?

Did you have the slide out? If so, did the vacuum plate get put in square side down? Does your hot start cable have some free play? New fuel screw? A little more info:thumbsup:

Did not have the slide out. I'm going to take another look at the hot start and fuel screw. Thanks.
