No, the only problem resides on a proper tune of your engine.
Firstly set the HSNV to the most revs. You can get, and then richen it turning 1/8 of turn backwards at a time.
Then you have to set the LSNV, the goal here is that the engine transition from low idle to WOT very smoothly, if it becomes rough and quits then I bet that your LSNV is way to open try 1/8 turn to lean the mixture and see if the transition goes better. This task could be tedious but you will get to a point where the engine transition smoothly from idle to WOT. Then recheck the HSNV and you are ready.
One more note: if the LSNV is too lean the engine will quit as well so you may try richening the mixture if the problem is worst, but as I imagine I bet that you will have to lean the LSNV.
