I bought my GST a couple of months ago and i email cen support to get a fuel recommendation and they confirmed the Byron's 30% mitro 11% oil so thats what i bought to break her in. During break-in i richened 1/2 turn from where it was stock then proceeded with break-in. On my sixth tank (last break -in tank) i started 1/2 throttling and then would temp and i was already running at 230 and that a 1/2 turn out from stock. so i left it there and started running alittle harder which sustained a even 240 until my tank started getting empty then it retard leins out. I bought the NOVA head for it which help out a bunch but im wondering if the 30% nitro with only 11% oil is hard on that motor. Should i change fuels and if so what do you guys suggest. I live on the texas coast so im less than 50' above sea level which i know liens out alittle more but its also 80% humidity all year.

thanks,
