drz fcr 39mm problems


Recommended Posts

I have a newly acquired 2001 drz400 with ( I think) an fcr 39 on it. It will run for 5-10 minutes and then die, and I'm not able to start it for at least 10 min. I'm in the process of cleaning the carb now but was just wondering what else could be wrong. The guy said he's never had problems with it but it did sit for awhile before I got it. It's definitely a used fcr carb and I don't know much about it.

Put the carb back on after only the cleaning and doesn't run very well and I can't adjust the fuel screw (seems to just keep turning with a screwdriver).  I'm ordering an extended fuel screw(which includes the o-ring and spring), and a new pilot jet.  The leaking fuel is a real slow drip coming out of the nipple on the bottom of the bowl, not too sure on how to fix that problem while I'm waiting for the parts.
