problem with idle speed

[chaixi]

I had a baotian bt qt-9 for 2 month and I did derestriction.

I had this problem for 2-3 weeks now. I did ask for some help on here. but I still can't find the problem.

It stops when I stop at the traffic light, it works ok on the main stand, only happen after riding for 5-10 mins.

I readjust the ilde screw, mixture screw, change the oil.

I havn't try the value set yet.

anybody have some more idear about this?

please help me!

And I checked my black rubber in the carb is no damage.

Did you clean out both sides of the rubber diaphragm and make sure the carb was clean?

Worth checking the valve clearances

when you say the carb is clean, do you need open the carb to see or just take the black rubber out and see if it is clean under it?
