XR250 Carb Question

I have an XR250 that's been sitting a while so I decided to clean out the carb.  In the jet labeled in the manual as the slow jet there is some sort of partial obstruction. I can't push a wire through it easily but it will pass air. Can this be right or should I get more aggressive clearing it out.

 

Thanks

It's a very small hole in the slow jet, I use a small strain or copper wire. If you can blow air through it then it should be clear.

It's probably gummed up, very common.

Shoot carb cleaner throught it for a while, then rotate the wire around inside. Force it if you have to.

A new jet costs $5 so no big deal if you can't get it cleaned. Sometimes the slow jets are hopelessly clogged.

Sure, get more aggressive with it, but don't discount the option of just spending $7 and buy a new one.

After spending time cleaning out small pilot jets, I found a new jet was worth the $7. I just couldn't get them clean enough with the new ethanol gas issues. It really kills small bike carbs. I use to own an xr400, 200, 100, 80, and SL100. The small bikes wouldn't even run until I put in new pilot jets.

Think about mixing Stabil in the gas before storage and drain the carb. I never use to, but I do now.

Thanks guys.  We got it running today. Still has some carb issues but we're on the way to getting it right.
