most of those 2 cycle carbs require a special tool similar to, but not exactly a screwdriver to adjust the screws
what kind of a head is on the adjustment screws?

The new carb will have the limiters. If you can get the tool it will likely cost as much or more than the carb, they are not supposed to be sold to service shops or the end user.

I got a set of 4 different adjusters for about 7 dollars on ebay...it was shipped within the US...there is a set of 8 on ebay from china for 2 dollars with free shipping....probably take about a month to get it

In the meantime you can jam a solderless, crimp type of wire connector ont the end of a screwdriver and use that..it slips some, but it will work in a pinch
