I have tried the carb sync method of shorting out each cylinder, but I'm not experienced enough to detect the sound differences, so I thought I would try this method. Now the online forums recognize this technique, but argue that it is less effective given it is only measuring vacuum differences. I thought I would give is a shot, and for $4 buck it can not hurt at this point to get the vacuum right.
I built my tool from parts from Lowes, 3.87 in tubing, and a yard stick. I used motor oil, because that is what I had sitting around.
PICTURE OF TOOL HERE
I built the tool ,and hung it from the garage door railings over night to let the oil settle to the the bottom on the tubing. The next day went for a 30 min ride, and came back in synced the carbs at idle, using the idle screw stop.
I will need to sync the carbs with the new throttle cables, but I need a second set of hands which are not here right now.
