First, thank you for answering my questions, knowing that the goal is to learn from your experience. In fact, I have developed a dynamic balancing system based on the technique of influence coefficients, which requires the use of a trial weight, and it has given very amazing results.However, I am currently researching a method used by the Vibrex 2000 and Dynavibe to locate the of the imbalance. Correction counterweight (Vibrex 2000 & Dynavibe)= (power (hp)/10 +30)*IPS.
When I was kid I used to watch a guy that specialized in front end auto repair balance car wheels by spinning a front wheel with a motor that pressed against the tread. He could tell how much weight to add by the feel of the fender. The he would find the correct spot by trial I thought about the weight I added, the holes in the flywheel accept 1/4 bolts and have to have a locknut to prevent loosening. I used the shortest bolt possible and it balanced first try. Its not unusual for me to use 2 bolts in adjacent holes and multiple washers to get a balance.
the place to install the counterweight is 8:00 (2:00+6) Why did you choose 7, knowing that this is a system that allows the weight to be divided into two locations by projection in the event that there is no place to install it?
I'm not used to talking and explaining what I'm doing with video running. You are correct the weight should have been added to 8. I probably did not have the optical target lined up either because I didn't want climb on the wing. If I had installed less weight at second run the phase shift if any would help me better locate the light spot better.
I just randomly picked the weight from experience doing many balances and it happened to work, just lucky. I thought it wouldn't be enough weight because I was adding the weight directly to the flywheel. I usually get it closer faster by guessing at the first weight
Well done!

The solution to the degree of imbalance 0.15 IPS is 7.2 g for a 180 horsepower engine. Why did you choose 10.7?
