Homemade Dyno, small engine DIY dynamometer

I&been discussing many things with DIY dyno groups and people with similar machines to get the most accurate break in and test procedure as can find! I will be making minor adjustments as listed in the video, based on what I find to be best! I&going to be tuning engines for go karts, race kart engine tuning and mini bikes.

I&still got my Tillotson 212r race engine video to compare to the Predator 212 non hemi engine, but the Tillotson...
