The adjustment screws are under those black caps in the picture. They may be slotted, splined, half round or some other shape. To adjust them, first find out their shape, then you may be able to find the proper tool. O'Rieleys has a tune kit that may work. You can thank the epa for the weird shapes, they think that they can bring about cleaner air by making it difficult to adjust the carbs andhave mandated the strange shapes to the manufacturers.
Looks like I'm going to have to do what you posted in second. I have a dremel handy just have to find my disks.Can't really see thr tops of the adjustment screws ... but there are several ways that have been used to make adjustment "difficult"....
There were removable caps that covered adjustment screws...
There are also spline screws as covered in this video... HOW TO ADJUST The Carburetor on Weedeater XT260 Grass Trimmer - YouTube
and in this video is shown a way to modify the spline screws to allow for adjustment... How to adjust a 2 cycle Carburetor with "set Locked" Screws - YouTube
both video clips have some good adjustment info... :smile:KennyV
It is a special shaped mtd dealer only tool regulated by the EPA. Current regulations prevent the average person or non MTD dealers from owning the tool legally.
That seals it! They are getting dremelled.
