Jeg presenterer herved enda et lite bidrag (i.e. "stjÄlet" fra et annet Volvo-diskusjonsforum) om synkronisering uten spesialverktÞy, for de som fortsatt er interessert i dette tema....:-)
"Synchronizing" the carbs. This impressive sounding term, which sounds as though it was borrowed from NASA, is the source of much confusion, profit to purveyors of unusual looking "special" tools, and more discussion than New England weather. I don't see the big deal...it seems intuitive that the two carbs need to be doing the same thing at the same time...so after assuring that the linkages act upon the throttles at the same time, the carbs should be dynamically "synched" (an even more impressive term!), that is, throttle idles adjustment screws should be adjusted such that at idle, the induction of the carbs is as close to equal as possible. This will result in a nice even, smooth idle. A number of devices are available to help with this equalization, and I too own a couple of them...the Unisync and Tuning Tool Set...but I find that these NEVER make it out of the toolbox anymore! I prefer instead to use my own original equipment for tuning...and I have this with me ALL THE TIME! I use my eyes and ears! I look at the height which the dashpot is raised, and I might stick my head down between the two carbs to better listen and compare the wonderful sucking noises.
* (Hypothetical questions: What's the difference between a visual indication by a little indicator button being sucked up the tube of a Unisync, for instance, vs. the dashpot of the carb being sucked up? Why would you trust a separate indicator tool more than the actual carb?)
