What I don't get is our EPA (US) ban on the repair shops getting carburetor tuning tools; unless, we have a very expense exhaust gas analyzer. They rather us to install a supposedly pre-tuned two cycle carburetors that are badly out of tuned that result a high polluting engine. We can not get a single tool from the OEMs. At least thank to the Chinese I have be able get most of those adjustment tools so thing are tuned right when they leave my shop.
