those auto start accelerators are crazy arnt they..

 

Sounds like an air leak, check reeds, carb boots for cracks, reed gaskets

your either running your bike too lean or your have an air leak.  Which is causing your bike to "lean rev" or begin to "run away" as a result.  Most 2stroke motors will run away when they are starved on fuel. 

 

What are your mods to your bike and what elevation and carbs are you running.....and what jets do you have in your carbs?

x2 on the air leak. After checking your reeds and intakes for leaks I'd start fishing. One tried and true old school method is to get a can of carb cleaner and start spraying around what are supposed to be sealed surfaces. If you find a leak you will know it immediately the engine will respond. If this stumps start doing some research on a crankcase vacuum test. It will indefenitly FIND your leak for you.
