Already listed above, I experienced only a 30 minute wait and a slight initial nor swallow a wonder when it comes to carburetor cleaning. OK, I have the mixing ratio - according to other statements on the net - slightly sharper recognized as it is on the guidance (double concentration) but the effect was just super. After a stoppage of almost 5 years with no tank drained (previous owner presented the only Diva aside) awakened the engine of my "new" now 20years old XJ600 Diversion to life. Were there previously just a more lasting No startup (Sprang barely, and then with interruptions - reason for a bargain purchase) and a then nonexistent throttle response (despite new fuel), so sign up now 4 cylinders quite good already at the slightest pressure joyfully in my ears on the starter. I had to have bought previously but still expected after the long time a US cleaning the carburetor Bank as a task with the machine, so I was with this small Invest (Learning by doing) but more than happy. Only now what are still present, the valves and carburetor synchronization is then equal to room. Then the first right exit, nothing can stand in the way.
