High speed needle setting on MR-12

My problem is that my running time is less than 5mins (I need at least 5mins as that is a standard round at my track), on my car as I have to run rich, or else the cars starts to bog down? I am running 20%, and running the standard plug?

Can someone help me please?

Thanks

Sami

is your motor bogging down because it gets to hot or when its rich???

there is no real setting for these engiens!!!

this problem could be your plug, temp of day, sea level!!!

No I just the stock motor, no turbo button? Are you running one, is it better and where can I buy one?

Thanks
