Kit per controllo della carburazione
Buon prodotto per fare la carburazione. Ti permette di effettuare le regolazioni necessarie e capire bene o male in che condizioni è il motore. Facile nell'utilizzo. Io l'ho usato per carburare una 500 d'epoca.

Simple to use and accurate enough to get you going. Takes some of the Voodoo out of carb tuning :)
I bought this because as a novice, after doing online research, I was feeling somewhat intimidated about tuning the carbs on my MGB roadster and I thought that this would provide me with an "easy" solution. And it did :) It seems that it is a bit of a "Marmite" product that you either hate or love. More experienced vintage car enthusiasts claim that it is inaccurate and unnecessary while other, probably less experienced owners, love it for its simplicity. I am a believer. It is incredibly easy to use and allowed me to tune my carbs to a significantly better state quickly and without stress. As a side benefit, it also provides you with the pretty cool opportunity to actually see the bang going on inside your engine! :) Remember that if you have a multi-carb engine, you will need to use this on one cylinder being fed by EACH of the carbs One caveat. The colortune is only an indication of fuel/air mixture combustion and therefore, in my opinion, does not replace a full carb tuning an balancing process. It does however give you the opportunity to easily get a close approximation to improve your ignition burn and running. In my case it also removed the vooodoo factor and made me more confident to then learn to fully tune the carbs on my car.

Meine Empfehlung zum Vergaser einstellen.
Ich kann nur sagen das diese tolle Glas Zündkerze super funktioniert, man kann die Verbrennung wunderbar sehen und auch die Veränderung wenn man das Gemisch am Vergaser einstellt so das die Flamme nicht mehr gelb sondern schön blau wird. Kann es nur empfehlen habe sie bei einer Dnepr und eine Harley Davidson benutzt und es hat hervorragend funktioniert so das die Zündkerze nach der Probefahrt schön rehbraun war.
