    To me the JetLab sounds closer.  I don’t think I had anything in my toolbox bigger than a 158 when we ran pre-evo engines around here.  152-158 during the winter, and 145-150 during the summer was our range.

    I bet your correct. The kart is being stored at my nephews right now but I will have to check and see if we recorded our setups and I still have them. I did find one instance of using a 162 at IMI in Oct in some notes, not to say it was correct just what I noticed. Probably the big indicator will be my jet box and which ones are worn the most from changing. I’m just really gun shy of sticking the old motor as I bet a rebuild is expensive now (used to be ~$700 for a top end replacement).
    Thanks for the reply,
