Hi,

Bought 2005 kazuma 250cc utility cvt. Does not hold idle well and will generally slowly die when gas is released or auto choke closes.

When running it will bog down a little on the low end, runs fine with throttle above 1/4 to fully open, but will still die when throttle is released. Seems to improve somewhat once warmed up.

Prior owner seems to have idle screw all the way in, probably to try to resolve the idle problems.

Spark plug in it is a ngk dr7es, looks like it should be a ngk d8ea, unsure if that is an issue or correct. Gapped to .028, unsure if that is also correct.

Cant find a manual online, any help would be appreciated on finding one.

I will pull carb and clean, but would like a manual prior to pulling apart or messing with air/fuel mix screw.

I have searched this site and must say it rocks.

when you pull that carb apart, plenty of videos on youtube, just pay close attention to what goes where. it is not hard. just make sure the orifices on the jets are clean and that the throat is clean, longways down the jet, on both jets.......then we can eliminate jets and go from there on your idle problem. but this may rectify the situation.
