once again I have read all the posts and some say to do a plug chop and some say that isn't accurate cause it takes hours for your plug to turn color, I have a long field with a slight incline where i could run it out and see what it runs like wide open but will it hit the rev limiter? i have jetted lots of 2 stroke sleds and that is how i found my main jet size to big and it will bog to small and it will hesitate any suggestions? thanks
